Remove support for old gcc versions by unconditionally defining
__MATH_BUILTIN_RELOPS and __MATH_BUILTIN_CONSTANTS. Per kib's request,
don't #undef those so it's easier to understand what the builtins are

This reverts commit 1a968da448.
I was mistakenly looking at the version strings in the CVS attic
but the function was moved to libc/stdio where it matches the
current string.
This change introduced a test failure, so revert until that can be
addressed.

There's no reason why the virstor chunk size needs to relate to MAXPHYS.
Remove it. Instead, just make sure that the chunk size is a multiple of

During the initial label of a virstor device, write out the allocation
map in chunks if it is large (> 1 MB) in order to avoid large mallocs.
Even though the kernel virstor geom may still do a large malloc to
represent the allocation map, this may still be useful to avoid a
ulimit.

The use of SYS_sigreturn is unnecessary here.
If handle_signal is called when a signal is delivered, it can just
return normally back to sigcode which will call sigreturn anyway.
In case handle_signal is called by check_deferred_signal, using
setcontext is better than SYS_sigreturn because that is the correct
system call to pair with the earlier getcontext.

It seems that there are still some applications that use ftime(3)
(for example, science/siconos and sysutils/lcdproc). The issue
is that we don't build libcompat as a shared library anymore.
The easiest solution is to move it to libutil, until we
deprecate it for good.

There is some exotic conditional logic here to avoid building a
particular test if a certain UBSAN library isn't present in the
toolchain sysroot. This causes build failures for me when doing an
"installworld WITHOUT_TOOLCHAIN=", which I do frequently during tests.
I believe the problem is that SYSROOT is unset during installworld, so
the build sees the host's copy of libclang_rt.ubsan_standalone.a and
then tries to install a binary that wasn't built during buildworld. Try
to make the check a bit less fragile.

The functions like gmtime(3) expect to cache a GMT time zone. Some
sandboxed programs (like last(1)) use the gmtime(3) function.
In case of last(1), this function fails to load a proper time zone

This time zone is not loaded by the tzset(3) function. Because of

GMT time zone. There is no other way to cache this data than
calling gmtime(3) once.

fts has different types for its compare rotuine. Other systems, not
4.4BSD based, have a non-const version. Before we tested against
__GLIBC__, but now we test against __linux__ because that's Linux's API
and musl doesn't define __GLIBC__.
In addition, link against libftl on this platform since musl doesn't
include ftl routines in libc, but rather in libftl.

mixer(8)'s -a option is used to print information about all mixer
devices in the system. To do this, it loops from 0 to
mixer_get_nmixers(), and tries to open "/dev/mixer%d". However, this
approach doesn't work when there are disabled/unregistered mixers in the
system, or when an audio device simply doesn't have a mixer.
mixer_get_nmixers() calls SNDCTL_SYSINFO and returns
oss_sysinfo->nummixers, whose value is the number of currently _enabled_
mixers only. Taking the bug report mentioned below (277615) as an
example, suppose a system with 8 mixer devices total, but 3 of them are
either disabled or non-existent, which means they will not show up under
/dev, meaning we have 5 enabled mixer devices, which is also what the
value of oss_sysinfo->nummixers will be. What mixer(8) will do is loop
from 0 to 5 (instead of 8), and start calling mixer_open() on
/dev/mixer0, up to /dev/mixer4, and as is expected, the first call will
fail right away, hence the error shown in the bug report.
To fix this, modify oss_sysinfo->nummixers to hold the value of the
maximum unit in the system, which, although not necessarily "correct",
is more intuitive for applications that will want to use this value to
loop through all mixer devices.
Additionally, notify applications that a device is
unavailable/unregistered instead of skipping it. The current
implementations of SNDCTL_AUDIOINFO, SNDCTL_MIXERINFO and
SNDCTL_CARDINFO break applications that expect to get information about
a device that is skipped. Related discussion can be found here:
