6879fc8942 Makefile: Avoid sanitizing PATH on non-FreeBSD systems
Allow the build process to find host binaries during the host-symlinks target when
cross-building on non-FreeBSD systems. Whilst most non-FreeBSD systems have all
the needed tools in /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin (the final
path added by host-symlinks itself), Homebrew for macOS on Arm defaults to
/opt/homebrew/bin, other more niche systems may also deviate and users may
expect tools in a customised PATH to be picked up, unlike on FreeBSD where we
want to ensure everything comes from base. In particular, (un)xz are needed
from Homebrew on macOS, and thus cannot be found on Arm without this.

Note that non-FreeBSD builds enforce BUILD_WITH_STRICT_TMPPATH, and so the
actual main build steps will still use a sanitised PATH.

These targets generate a raw list of the candidate old files roughly
corresponding to the values of OLD_DIRS, OLD_FILES, and OLD_LIBS.
Currently list-old-files also includes uncompressed manpages in
addition to compressed manpages.

Use these targets in the implementation of check-old-* and

16aa4787ca Remove 'make update'.
In the CVS days this used be a wrapper around either CVS or CVSup and
used to support updating src, doc, and ports checkouts.  With the move
to subversion this only supported updating src and was itself a
wrapper around 'svn update'.  With Git, users are probably better off
using appropriate Git commands directly to update without needing an
explicit make target as a wrapper.

502fa11ee8 Makefile: Fix MAKEOBJDIRPREFIX command-line variable check for bmake
Unlike the old fmake, running make FOO=bar when using bmake doesn't put
FOO=bar in .MAKEFLAGS at the top level, it instead just puts FOO in
.MAKEOVERRIDES and the full MAKEFLAGS will be formed for sub-makes.
Moreover, this only applies for sub-makes in rules, so this doesn't
apply to those in shell assignments. This means that the current check
does not catch make MAKEOBJDIRPREFIX=..., only those defined in config
files. Thus we must also check .MAKEOVERRIDES explicitly.

0ac8aa55da pkgbase: Add incremental packages
This adds a new target update-packages which will create the new packages
compared to the last run.

This is how to use it:
At this point we cut a release
$ make buildworld ...
$ make buildkernel
$ make packages

    There is now a PKG_VERSION directory with latest link pointing to it
    Distribute the packages to server

$ something something that update the source tree
$ make buildworld ...
$ make buildkernel
$ make update-packages
You know have a PKG_VERSION directory in the REPODIR and latest link pointing to it.
In PKG_VERSION dir only the packages which differs from the latest run are
named PKG_VERSION, otherwise the old packages are there.

The process is :
Build the new packages in the PKG_VERSION directory
Compare the internal data with the PKG_VERSION_FROM version. The comparison is done
by checking the internal hash of the packages.
By default PKG_VERSION_FROM is set to what the latest link points to.
If the old and new version matches, we rm the new package and cp the old one.

7d0c2b1131 Add a USE_GCC_TOOLCHAINS knob to make universe.
This uses GCC toolchains instead of LLVM on architectures supported by
GCC.  Currently this uses GCC 6 on aarch64, amd64, i386, and mips.

Although this does also try to use GCC 6 on powerpc, it is always
skipped for now since a powerpc-gcc6 package is not available and the
structure of make universe makes it hard to skip a subset of arches
for a target.  This should be short-lived as freebsd-gcc9 does include
a powerpc-gcc9 package so powerpc should work once this switches to
GCC 9.

b19042cb01 Use universe-toolchain config(8)
This is a temporary hack to aid with config(8) changing in r360443.
It will not work for all cases.

env PATH is used because universe-toolchain is only built when worlds
are built, and then only if clang is needed, so it may not exist.

universe-toolchain needs to be expanded to always be built, inspected to
remove non-cross-build-safe tools, used for buildworld/buildkernel,
and potentially incremental build support.

c9870c1542 Fix make kernels to match original commit message
make kernels was originally documented (in commit r295099) as the same as make
universe -DJUST_BUILD_KERNELS. However, it used the UNIVERSE_TARGET=buildkernel
which is subtly different in that it also builds the toolchains and doesn't
build the LINT modules unless they happened to already exist in the tree. This
unbreaks POLA and just builds the kernels, including LINT, now rather than all
that other stuff as well. When the commit originally happened, the two just
differed by the LINT bug. r335711 introduced the universe dependency on the
toolchain that wasn't present before, which diverged the two further. This
restores the original intent of r295099.

0b2b53a2ea Only build kernels for enabled TARGET_ARCHes in make universe/tinderbox.
Previously, all of the kernels for a given TARGET were built if that
target was enabled.  This was implemented by having each kernel built
via a universe_kernconf_<KERNEL> target that was depended on by a
universe_kernconfs target.  However, this meant that if one did a
build with a limited set of TARGET_ARCH values for a given TARGET,
kernels could be built for which we hadn't built a world or toolchain.
For example, 'make TARGETS=mips TARGET_ARCHES_mips=mips64' would build
mips32 kernels.

Fix this by adding an extra layer of indirection in the kernel make
targets.  universe_kernconf_<KERNEL> is now a dependency of a new
universe_kernconfs_<TARGET_ARCH>.  universe_kernconfs in turn depends
on a list of universe_kernconfs_<target_arch> values, but only the
values enabled in TARGET_ARCHES_<TARGET>.

Bump __FreeBSD_version to 1300073

Tested with make universe. Any stale LINT-V5 config files remaining in the tree
will fail the universe build. However, LINT-V5 was removed in r355119.

This retirement has been planned since last summer. The armv5 port is fragile:
it works OK for some peeople, and fails badly for others. There's a number of
subtle bugs in busdma, pmap and other MD parts of thee system that present
themselves under load or in unusual circumstances (like fsck after a
crash). stable/8, branched 10 years ago, was the last reliable release.  Since
the support burden is larger then the benefit, the consensus view is armv5
should be removed from the tree.

b411a285d9 Disconnect powerpc from the default tinderbox for now.
The wrong toolchain was set in MAKE_PARAMS_powerpc, however, there are
some other issues preventing powerpc from building in tinderbox:

1) There is no powerpc-gcc and powerpc-xtoolchain-gcc port that
   provides an external 32-bit powerpc GCC toolchain.

2) On other targets, the same toolchain can build all of the
   architectures for a given target.  MIPS achieves this by always
   setting -mabi and -EB/-EL explicitly instead of relying on the
   compiler's default architecture.  PowerPC might be able to do the
   same thing, but as of today, powerpc-gcc would be required for
   powerpc and powerpcspe and powerpc64-gcc would be required for
   powerpc64.  Our existing logic for make universe does not permit
   per-MACHINE_ARCH toolchains.

I tried hacking TARGETS_powerpc to only include powerpc64 when
powerpc64-gcc was present, and while that skipped the 32-bit worlds,
it tried to build all the kernels.

8f62bca488 Allow building world without inheriting $PATH
Inheriting $PATH during the build phase can cause the build to fail when
compiling on a different system due to missing build tools or incompatible
versions somewhere in $PATH. This has cause build failures for us before
due to the jenkins slaves still running FreeBSD 10.
Listing the tools we depend on explicitly instead of just using whatever
happens to be in $PATH allows us to check that we don't accidentally add a
new build dependency.

All tools that do no need to be bootstrapped will now be symlinked to
${WORLDTMP}/legacy/bin and during the build phase $PATH will only contain
${WORLDTMP}. There is also a new variable "BOOTSTRAP_ALL_TOOLS" which can
be set to force compiling almost all bootstrap tools instead of symlinking
them. This will not bootstrap tools such as cp,mv, etc. since they may be
used during the build and for those we should really only be using POSIX
compatible options.

Furthermore, this change is required in order to be able to build on
non-FreeBSD hosts. While the same binaries may exist on Linux/MacOS they
often accept different flags or produce incompatible output.

When both SYSTEM_COMPILER and SYSTEM_LINKER logic passes then libclang
will not build in cross-tools.  If either check fails though then
libclang is built.

The .info is reworked to notify when libclang will be built since if
either clang or lld needs to be rebuilt, but not the other, the
notification can lead to confusion on why "clang is building".

-fuse-ld= is not used with this method so some combinations of compiler
and linker are expected to fail.

A new 'make test-system-linker' target is added to see the logic results.

Makefile.inc1:
  CROSS_BINUTILS_PREFIX support had to be moved higher up so that XLD
  could be set and MK_LLD_BOOTSTRAP disabled before checking SYSTEM_LINKER
  logic as done with SYSTEM_COMPILER.  This also required moving where
  bsd.linker.mk was read since XLD needs to be set before parsing it.  This
  creates a situation where src.opts.mk can not test LINKER_FEATURES or
  add LLD_BOOTSTAP to BROKEN_OPTIONS.
