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.

This fixes a warning for each RISCV target during universe by passing in
the required CROSS_TOOLCHAIN setting which will in turn set
CROSS_BINUTILS_PREFIX correctly. It also ensures that a tinderbox build
uses the correct compiler for riscv. Previously it was using the shared
clang compiler instead of riscv64-gcc.

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 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.

There's no reason to create object directories for targets like 'installworld'
or 'distributeworld', and the others in this list. Specifying MK_AUTO_OBJ as a
make argument allows circumventing this if needed for some reason.

- 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.

Without this the user has to mess with 'make -f Makefile.inc1 ...' to figure
out where the files are installed in the OBJDIR and then they need to copy them

Make armv7 as a new MACHINE_ARCH.
Copy all the places we do armv6 and add armv7 as basically an
alias. clang appears to generate code for armv7 by default. armv7 hard
float isn't supported by the the in-tree gcc, so it hasn't been
updated to have a new default.

TARGET_ARCH).

It appears that the same arches that lack GENERIC kernel configs also lack
LINT. But enough different arches get built to ensure a kernel change
should build everywhere (32 and 64 bit, clang and old gcc, little and big
endian).
just the GENERIC kernels for each arch (including variations such as
GENERIC-NODEBUG, GENERIC64, etc).
This helps with quickly doing a test build for all[*] arches without
building dozens of variant kernels for the arches that have lots of
hardware/board/system variations.
[*] Not all arches have a generic kernel (but they probably should for
test-building purposes, even if it can't boot on any real hardware).
Normally META_MODE ignores host files for "meta mode" decisions on whether a
file should be rebuilt or not. This is because a simple installworld can
update timestamps and cause the next build to rebuild all host tools, when the
previous ones may not have any changes in the source tree. These tools are
normally still ABI compatible. They are only rebuilt if NO_META_IGNORE_HOST is
set from the workaround/hack in r301467.
One of the major problems with this is when a host tool has objects spread
across many revisions that have mixed-ABI. For example, if struct stat were to
change on the host, some objects for a tool may have different ideas of that
struct's definition. If just 1 source file were modified and rebuilt and
linked into the tool, then that toll will have mixed-ABI objects and crash.
This exact thing happened with the ino64 commit in r301467 followed by a
trivial update to libbfd in r318750. The resulting binary would crash in
buildworld.

Right after cross-tools, a compiler-metadata.mk file is created that
stores all of the bsd.compiler.mk metadata. It is then read in
with a fail-safe during installworld time.
The file is explicitly removed when invoking cross-tools to ensure that
a stale file is not left around from odd manual 'make _cross-tools' ->
'make installworld' invocations.
This fixes several issues:
- With WITH_SYSTEM_COMPILER (default yes on head and no on releng/11.0):
If you build on a system where the bootstrap compiler does not
build due to the host compiler matching the in-tree one, but then
installworld on another system where that logic fails (a
bootstrap compiler is needed), the installworld immediately fails
with:
sh: cc: not found
Note that fixing this logic may then hit a case where a rebuild is
attempted in installworld. Normally cc would be ran with
'CFLAGS+=ERROR-tried-to-rebuild-during-make-install' to cause an
error such as:
cc: error: no such file or directory: 'ERROR-tried-to-rebuild-during-make-install'
However, now it will just fail with the 'cc: not found' error.
Inspection of the compile line will show
'ERROR-tried-to-rebuild-during-make-install'; It's not useful to
set CC to anything other than 'cc' during install as it is more
helpful to see the attempted compile rather than some other bogus
error.
- This now avoids running bsd.compiler.mk (cc executions) even more
during installworld. There are compiler-dependent SUBDIR in the
tree which required having a compiler during install.
There is at least 1 case where CC is still executed in the install,
such as from a LOOKUP!= in secure/lib/libcrypto/Makefile.inc checking
for 'vzeroall' support. This is not significant for installworld
as the lookup has a fallback (and hides its error) and only modifies CFLAGS,
thus it's not worth fixing.
