This code, which is basically `svnversion || svnliteversion`, generates
2 fstatat(2) for every directory in PATH for every Makefile parsed that
includes bsd.own.mk. This can add up for things like generating a Ports
index (Poudriere) or building a dependency graph for base.

bsd.compiler.mk. It's so fmake from older 9.x systems still
works (still a supported build config, and having the note here
will let us know when we can cull it more easily).
Also pull in a related change from include to sinclude from
arichardson@'s cross building work, as well as it's companion in
Makefile.inc1 with a note about why we do the odd thing there.

A comment in Makefile.inc1 has long stated that LOCAL_DIRS are built last,
after the base system. Incremental improvements in parallel building over
the years have led to LOCAL_DIRS being built in parallel with base system
directories. This change allows the .WAIT directive to appear in LOCAL_DIRS
and LOCAL_LIB_DIRS lists to give the user some control over parallel
building of local additions.

Because we force enable MK_GCC when building we need to also force
enable it for the cleaning phase. Otherwise the NXB_TARGET files
are found in the next build's kernel-toolchain phase and cause
an error.

The initial kernel-toolchain is built with TARGET=MACHINE but
we want GCC to have files generated for TARGET=NXB_TARGET
instead later on. Just clean the files between building of
the toolchain and nxb binaries which will let it rebuild

Packaged base packages are created by running the stageworld and
stagekernel targets with -DNO_ROOT, and converting the resulting mtree
file into a set of pkg plists. If stage* is run with multiple processes
the order of entries in the mtree file may be nondeterministic, and the
resulting package tbz also had nondeterministic file ordering.
The mtree file generated by -DNO_ROOT builds consists of one line per
file, with the filename starting in the first column, so is easily
sorted. There's one exception: the first line of the mtree file is a
comment, but the # character sorts before the filenames anyhow and needs
no special treatment.

- This also adds in a _cleanobj step as needed.
- This redirects TARGET/TARGET_ARCH to NXB_TARGET/NXB_TARGET_ARCH in
Makefile.inc1 as the main build needs to be for MACHINE rather
than TARGET.
First build the toolchain and then use that as an external toolchain
to build the needed directories and NXB_TARGET-toolchain, all as
MACHINE files though via TARGET_TRIPLE=MACHINE_TRIPLE.
The NXBDIRS is evaluated in the 'everything' submake as it needs to be
based on TARGET's src.opts.mk values, such as MK_GCC=yes when building
on a MK_CLANG=yes MACHINE. This can likely be changed to a specific
_native-xtools-everything target later and the funky late evaluation
of SUBDIR_OVERRIDE removed.

- If OBJROOT is SRCTOP then don't add on TARGET.TARGET_ARCH. This
only happens at the top-level, and for sub-directories when the
user is clever with MAKEOBJDIRPREFIX=/.
- Don't bother checking 'test -w' on .CURDIR.
- Properly set OBJTOP/OBJROOT to SRCTOP in various needed cases.
- Check if the OBJDIR is writable even for *clean* targets since it
determines which .OBJDIR the user gets; If they cannot write to an
existing eligible .OBJDIR then it needs to clean in .CURDIR instead.
- Add guard to cleanworld/cleanuniverse from removing SRCTOP.
- Ensure OBJTOP is proper for .OBJDIR=.CURDIR which fixes finding
libraries since src.libnames.mk is based on OBJTOP.
- Avoid some chdir(2) for modifying .OBJDIR

This problem was caused by r325329 and r325350.
For the release(7) targets, some will run mm-mtree.sh which itself runs make
with a MAKEOBJDIRPREFIX. The execution of that script leaks OBJROOT,
MAKEOBJDIR, and MAKELEVEL=1 in the environment. This causes the mm-mtree makes
to not do some basic setup of OBJROOT and only use this special
MAKEOBJDIRPREFIX case which fails to empty out MAKEOBJDIRPREFIX for further
nested makes, such as a tree walk. If that tree walk sets OBJROOT/OBJTOP such
as r325329 is doing, then the wrong OBJDIRs end up being used due to the
unemptied MAKEOBJDIRPREFIX being preferred over the proper MAKEOBJDIR.

NO_OBJ has a very specific meaning in sub-directories in that no object
directory will be made. If a user wanted to skip the 'make obj' phase then
passing -DNO_OBJ would break all sub-directories from building properly. Using
NO_OBJ internally also causes issue with NO_OBJ handling being added in
share/mk/bsd.init.mk soon.

This still keeps the reduced MAKEOBJDIRPREFIX (SRCTOP) redundancy
removed in the OBJDIR, but now keeps all early phase objects
in the same directory rather than split per phase.
The problem of splitting per phase is that later phases want to link in
libraries from earlier phases and base their location on ${OBJTOP}.

This will force any existing objects to rebuild if their .meta
files reference files from WORLDTMP. This is a problem after
the UNIFIED_OBJDIR effort caused buildworld and DIRDEPS_BUILD
to share an OBJDIR. Without cleaning these files the
Makefile.depend files end up with odd tmp/legacy/... entries
since some bootstrap-tools linger from there and otherwise
don't rebuild. Removing the files causes anything having
used WORLDTMP to rebuild.

Given MACHINE/MACHINE_ARCH=amd64, TARGET=arm64 and TARGET_ARCH=aarch64,

This changes the build OBJDIR from the older style of /usr/obj/<srcdir> for
native builds, and /usr/obj/<target>.<target_arch>/<srcdir> for cross builds to
a new simpler format of /usr/obj/<srcdir>/<target>.<target_arch>. This
new format is used regardless of cross or native build. It allows
easier management of multiple source tree object directories.
The UNIFIED_OBJDIR option will be removed and its feature made permanent
for the 12.0 release.
Relnotes: yes (don't note UNIFIED_OBJDIR option since it will be removed)

There's no good reason to treewalk the entire tree removing old OBJDIRS
and creating new ones when 'includes', 'libraries', and 'everything' are
all skipped. The only shared directory in the existing toolchain target
and world is build-tools. So handle cleaning in it directly if needed
only for the directories it wants to build.
The extra _obj/_cleanobj walks came in the initial kernel-toolchain
addition in r128189.
