A number of header files in sys/* have, going back to 7th Edition Unix
in 1979, reqiured other files (like sys/types.h) to compile. Likewise
the 4BSD networking code has had prerequisites. However, going back to
around the turn of the 21st century, other systems have made them be
independently include-able (wide-spread header include protection
post-dates 7th edition Unix by maybe 3 or so years judging from USENET
source postings). Start down the path of making them all independently
include-able by creating this test that fails buildworld when they are
not.
The file 'badfiles.inc' contains a list of the currently broken files
that cannot be included w/o any prerequisites. As files are fixed, 'make
badfiles.inc' should be re-run to remove them from the list. Note: All
files that start with an underscore are considered internal and not
tested.
Please note: once a file is removed from badfiles.inc, it must pass on
all architectures. Buildworld through at least the _includes target is
needed to ensure its working (though a buildkernel should also be done
on all architectures as well).

Unlike the old fmake, running make FOO=bar when using bmake doesn't put
FOO=bar in .MAKEFLAGS at the top level, it instead just puts FOO in
.MAKEOVERRIDES and the full MAKEFLAGS will be formed for sub-makes.
Moreover, this only applies for sub-makes in rules, so this doesn't
apply to those in shell assignments. This means that the current check
does not catch make MAKEOBJDIRPREFIX=..., only those defined in config
files. Thus we must also check .MAKEOVERRIDES explicitly.

This adds a new target update-packages which will create the new packages
compared to the last run.
This is how to use it:
At this point we cut a release
$ make buildworld ...
$ make buildkernel
$ make packages
There is now a PKG_VERSION directory with latest link pointing to it
Distribute the packages to server
$ something something that update the source tree
$ make buildworld ...
$ make buildkernel
$ make update-packages
You know have a PKG_VERSION directory in the REPODIR and latest link pointing to it.
In PKG_VERSION dir only the packages which differs from the latest run are
named PKG_VERSION, otherwise the old packages are there.
The process is :
Build the new packages in the PKG_VERSION directory
Compare the internal data with the PKG_VERSION_FROM version. The comparison is done
by checking the internal hash of the packages.
By default PKG_VERSION_FROM is set to what the latest link points to.
If the old and new version matches, we rm the new package and cp the old one.

This uses GCC toolchains instead of LLVM on architectures supported by
GCC. Currently this uses GCC 6 on aarch64, amd64, i386, and mips.
Although this does also try to use GCC 6 on powerpc, it is always
skipped for now since a powerpc-gcc6 package is not available and the
structure of make universe makes it hard to skip a subset of arches
for a target. This should be short-lived as freebsd-gcc9 does include
a powerpc-gcc9 package so powerpc should work once this switches to
GCC 9.

This is a temporary hack to aid with config(8) changing in r360443.
It will not work for all cases.
env PATH is used because universe-toolchain is only built when worlds
are built, and then only if clang is needed, so it may not exist.
universe-toolchain needs to be expanded to always be built, inspected to
remove non-cross-build-safe tools, used for buildworld/buildkernel,
and potentially incremental build support.

make kernels was originally documented (in commit r295099) as the same as make
universe -DJUST_BUILD_KERNELS. However, it used the UNIVERSE_TARGET=buildkernel
which is subtly different in that it also builds the toolchains and doesn't
build the LINT modules unless they happened to already exist in the tree. This
unbreaks POLA and just builds the kernels, including LINT, now rather than all
that other stuff as well. When the commit originally happened, the two just
differed by the LINT bug. r335711 introduced the universe dependency on the
toolchain that wasn't present before, which diverged the two further. This
restores the original intent of r295099.

Previously, all of the kernels for a given TARGET were built if that
target was enabled. This was implemented by having each kernel built
via a universe_kernconf_<KERNEL> target that was depended on by a
universe_kernconfs target. However, this meant that if one did a
build with a limited set of TARGET_ARCH values for a given TARGET,
kernels could be built for which we hadn't built a world or toolchain.
For example, 'make TARGETS=mips TARGET_ARCHES_mips=mips64' would build
mips32 kernels.
Fix this by adding an extra layer of indirection in the kernel make
targets. universe_kernconf_<KERNEL> is now a dependency of a new
universe_kernconfs_<TARGET_ARCH>. universe_kernconfs in turn depends
on a list of universe_kernconfs_<target_arch> values, but only the
values enabled in TARGET_ARCHES_<TARGET>.

Bump __FreeBSD_version to 1300073
Tested with make universe. Any stale LINT-V5 config files remaining in the tree
will fail the universe build. However, LINT-V5 was removed in r355119.
This retirement has been planned since last summer. The armv5 port is fragile:
it works OK for some peeople, and fails badly for others. There's a number of
subtle bugs in busdma, pmap and other MD parts of thee system that present
themselves under load or in unusual circumstances (like fsck after a
crash). stable/8, branched 10 years ago, was the last reliable release. Since
the support burden is larger then the benefit, the consensus view is armv5
should be removed from the tree.
Discussed with: arm@ mailing list and arm developer community.
It's on the chopping block in two months, the CI tinderbox doesn't bother with
it anymore either, and buildworld fails today due to an issue linking clang.
It's not worth investigating and it just eats up CPU cycles running universe
builds.
The wrong toolchain was set in MAKE_PARAMS_powerpc, however, there are
some other issues preventing powerpc from building in tinderbox:
1) There is no powerpc-gcc and powerpc-xtoolchain-gcc port that
provides an external 32-bit powerpc GCC toolchain.
2) On other targets, the same toolchain can build all of the
architectures for a given target. MIPS achieves this by always
setting -mabi and -EB/-EL explicitly instead of relying on the
compiler's default architecture. PowerPC might be able to do the
same thing, but as of today, powerpc-gcc would be required for
powerpc and powerpcspe and powerpc64-gcc would be required for
powerpc64. Our existing logic for make universe does not permit
per-MACHINE_ARCH toolchains.
I tried hacking TARGETS_powerpc to only include powerpc64 when
powerpc64-gcc was present, and while that skipped the 32-bit worlds,
it tried to build all the kernels.

if MAKE_OBSOLETE_GCC is defined. In all cases, explicit lists of
architectures in TARGETS= on the command line override.
For mips, powerpc and sparc64, do the same thing we do for risvc when
MAKE_OBSOLETE_GCC isn't defined and short-circuit their universe build
with an echo saying to install the xtoolchain port or pkg.

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.
