Need to handle LLD_BOOTSTRAP separately (for archs like i386).
This would be much better off with an off-by-default option like
SHARED_TOOLCHAIN that universe force-enabled. Then a normal buildworld
would store the toolchain there if enabled and otherwise in WORLDTMP
with only the 1 arch selected.

This will disable the new LLVM_TARGET_ALL option which will only
enable the required target.
This only impacts the bootstrap compiler in WORLDTMP, not the target compiler
that will be installed.

LLVM_TARGET_* will auto be set based on LLVM_TARGET_ALL and MK_CLANG.
If LLVM_TARGET_ALL is disabled, during a cross-build, then SYSTEM_COMPILER
and SYSTEM_LINKER are auto disabled.
This option should be used by users rather than the per-arch LLVM_TARGET
options as it is simpler to maintain for them should the supported
target list change.

Rather then combining hardlink creation for the geom(8) binary with
shared library build, move libraries to src/lib/geom so they are
built and installed normally. Create a common Makefile.classes
which is included by both lib/geom/Makefile and sbin/geom/Makefile
so the symlink and libraries stay in sync.
The relocation of libraries allows libraries to be build for 32-bit
compat. This also reduces the number of non-standard builds in
the system.
This commit is not sufficent to run a 32-bit /sbin/geom on a 64-bit
system out of the box as it will look in the wrong place for libraries
unless GEOM_LIBRARY_PATH is set appropriatly in the environment.

This works similar to WITH_SYSTEM_COMPILER added in r300354. It only
supports lld via WITH_LLD_BOOTSTRAP.
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.

MK_LLD is for the installed lld while MK_LLD_BOOTSTRAP is for the build
tool. For WITH_SYSTEM_LINKER it is necesarry to separate the logic of
these two. When building libllvm TOOLS_PREFIX will be defined and
MK_LLD_BOOTSTRAP should be checked instead.

LLD_BOOTSTRAP (build) is independent of LLD_IS_LD (installed) so they

This could lead to 'sh: head: not found' warnings which were a symptom
of running 'ld --version' during installworld. This was only happening
with XCC or XLD set. It is intended that cc and ld do not run during
installworld. The metadata for these are already stored in
compiler-metadata.mk added in r316794.
This also removes redundant CROSSENV additions that were for
WITH_SYSTEM_COMPILER, WITHOUT_CROSS_COMPILER, and WITHOUT_TOOLCHAIN
which all don't have a cc or ld in their PATH during install.

pmu-events: expand out skylake regex to simplify string matches
r307825 and r333017 disallow building FreeBSD-HEAD from 9.x or 10.x
versions that have some clang issues. The minimum supported Subversion
revisions and osreldates containing the fix are:
Version Min Rev osreldate
9.x r286035 903509
10.x r286033 1002501
9.3 is the final 9.x release and does not contain the r286035 fix.
10.3 is the first 10.x release with the fix. Thus, in practice 10.3 is
the oldest release that can build HEAD.
Although it may still be possible to build HEAD from an up-to-date
stable/9 it's not worth maintaining the special case when the branch
itself is unsupported and there are no usable releases from that branch.
Old UPDATING entries can be removed and the Clang warning in UPDATING
may be updated, in a future commit.

kernel.ucl uses a hardcoded boot/kernel for kldxref, which is the incorrect
directory when we're installing extra kernels that aren't the "default"
kernel (placed at boot/kernel).
Fix this by instead using a new %KERNELDIR% that we now replace in
Makefile.inc1 with "kernel" for the default kernel and "kernel.${_kernel}"
for these extra kernels so that, e.g. /boot/kernel.SHIVA, will get properly
kldxref'd upon update and avoid outdated linker.hints.
