The sparc64 architecture is being removed from FreeBSD 13, starting
now. This removes it from the top level only. It is the only
architecture that didn't see substantial work after the call to get
things working with the external toolchain.
All of the in-tree architectures not supported by in-tree binutils are
supported by lld, so the condition is now always false. It also
didn't fully work since the external binutils are installed into a
directory that uses the host's OS version, not the target OS version.

${WORLDTMP}/legacy/usr/libexec will only have libexec/ bits that we've
pushed as bootstrap tools, so this is generally safe to include prior to
PATH. The following are the ramifications of this change:
- BPATH addition gets us at least bootstrap flua in WMAKEENV path for
buildenv, for those earlier systems where it's bootstrapped still
- Reworked the sysent target to just set PATH and let it get worked out in
src.lua.mk or individual sysent makefiles -- this gives us back the
ability to overwrite LUA_CMD and use a different/external lua for these
targets. sysent can also now work cleanly in buildenv.
- tools/build/Makefile will now symlink the host flua into build's host
tools so that the above can work without needing to add the host's
/usr/libexec explicitly into TMPPATH.

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.

Some background: in the GSoC project, libbe/Makefile lived in lib/libbe. I
created projects/bectl branch, maintained the above for all of five
minutes before I misread Makefile.inc1 and decided that it couldn't possibly
build outside of cddl/, so I kicked the Makefile out into the cddl/ build
and all was good. The misreading was of the bit where .WAIT is added to
SUBDIR after lib, libexec but prior to building bin and cddl *only during
the install targets*, which is the critical part.
Fast forward- buildworld was still broken in my branch unbeknownst to me
because I didn't nuke my OBJDIR. Combing through Makefile.inc1 eventually
revealed the necessary magic to make sure that libbe's dependencies are
specified well enough, and it becomes clear what needs done to make a
non-cddl/ build work. This is an interesting prospect, because the build
split is kind of annoying to work with.
IGNORE_PRAGMA is added to avoid dropping WARNS by one more. This was
previously pulled in via cddl/Makefile.inc.
In the create-world-packages target we manually piece this together (unless
it is undefined), without the DISTDIR. Normally DISTDIR is empty (unset) and
no one notices. Now DISTDIR is a well known long-standing PORTS environment
variable and if that is set in the local environment the path to METALOG
is wrong as it no longer is ${DESTDIR}/METALOG.
Long-term we should start to avoid "publicly well known" names for global
variables, for now just piece ${DISTDIR} in as well. This allows
create-world-packages to continue if DISTDIR is set in the env.
There are several scripts and targets solely used to generate install

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.

Aligns the build with the FreeBSD traditional approach to not build in
contrib/, and to track inter-dependencies between libraries.

vendor provided pmu-events tables and sundry cleanups.
The vendor pmu-events tables provide counter descriptions, default
sample rates, event, umask, and flag values for all the counter
configuration permutations. Using this gives us:
- much simpler kernel code for the MD component
- helpful long and short event descriptions
- simpler user code
- sample rates that won't overload the system
Update man page with newer sample types and remove unused sample type.

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.
