This also fixes META MODE rebuilding these because the 'number of build commands'
changed from the previous build.

Extend it to other cases of meta mode cookies so they get the proper rm
cookie behavior when a .meta file detects it needs to rebuild and fails.

This obsoletes the _SKIP_BUILD check but keeps it for now until it
proves to be enough.
In the dirdeps build the first 'make all' or 'make' ran would invoke
'make dirdeps' which builds dependencies and then builds the current
directory in a sub-make (when BUILD_AT_LEVEL0 is no, which for us it
is). This behavior causes things attached to 'all:' to build in the
dirdeps phase AND the sub-make phase which creates all kinds of problems
for staging, meta file tracking, and races.

This also fixes meta tracking for the beforeinstall since it had been
marked .PHONY before (in bsd.sys.mk).

This is a follow-up to r291561 which reworked the bootstrap tool PATH
handling.
An example of this is when building lib/clang/libclangedit. At first
clang-tblgen will not be staged in the host tree so it will have
CLANG_TBLGEN=clang-tblgen set and exported. During the build though it
will stage clang-tblgen and then find it via the PATH. On the next
build it finds clang-tblgen in the stage directory and would set
CLANG_TBLGEN=<stagedir/usr/bin>/clang-tblgen thus causing the build
command to change. In both cases the same exact tool was used though so
there is no need to rebuild. If the tool did change the normal
meta/filemon handling would pick that up via timestamp comparisons and
rebuild.

An example of where this is needed is in share/examples which for
'etc-examples' runs 'make -C SRCTOP/etc etc-examples' which installs
to the default DESTDIR otherwise.

This came in r239572 for META_MODE handling but it doesn't make sense
since the staging is always done in make(all); make(buildincludes)
is never actually ran in the META_MODE build.

This file is using stage-install, so all of the .dirdep files
are properly handled. The cookie handling also properly
handles rebuilds with .meta files. DESTDIR from bsd.sys.mk is also
respected for staging. This logic came in r239572.

The meta file may decide the target is out of date but nothing
ensures that the *next* build will build this target if it
fails this time for some reason; it is still out-of-date
until it succeeds.
Convert the include/ cookie usage to the global versions.

Fix GCC atomic implementation in C++03
Pull in r250802 from upstream libc++ trunk (by Eric Fiselier):
Detect relaxed constexpr rules for gcc versions
Pull in r255585 from upstream libc++ trunk (by Eric Fiselier):
Fix various GCC mis-configurations for newer versions.
This patch goes through and enables C++11 and C++14 features for newer GCC's.
The main changes are:
1. Turn on variable templates. (Uses __cpp_variable_templates)
2. Assert atomic<Tp> is trivially copyable (Uses _GNUC_VER >= 501).
3. Turn on trailing return support for GCC. (Uses _GNUC_VER >= 404)
4. XFAIL void_t test for GCC 5.1 and 5.2. Fixed in GCC 6.
Together, these should fix building clang 3.8.0 as part of building
world with recent versions of gcc (e.g. the devel/*-xtoolchain-gcc
ports).
- Try to guess what is provided as a pin spec for -t or for get/set
operation: number or name. Fails in case of ambiguity.
- Add -p and -N switches to force pin specification interpretation:
-p forces spec to be pin number, -N forces it to be name

Fix most GCC warnings during build. Only -Wattribute left.
This helps to fix a number of -Werror warnings when building world with
recent versions of gcc (e.g. the devel/*-xtoolchain-gcc ports).
This fixes the following error:
kernel: error: [drm:pid1167:drm_release] *ERROR* Device busy: 2
Because of that, drm_lastclose() was not called, leading to a few memory
leaks once the driver was unloaded.

pfs_visible(). The recursion does not cause deadlock because the sx
implementation does not prefer exclusive waiters over the shared, but
this is an implementation detail.

At least FAST_DEPEND won't even run 'make depend', so the code was
potentially broken with FAST_DEPEND anyhow. The .dinclude directive
will ignore missing files rather than make them be fatal.
Sponsored by: EMC / Isilon Storage Division
The inclusion of .MAKE.DEPENDFILE (.depend) has special logic in make
to ignore stale/missing dependencies. bmake 20160220 added a '.dinclude'
directive that uses the special logic for .depend when including the file.
This fixes a build error when a file is moved or deleted that exists in a
.depend.OBJ file. This happened in r292782 when sha512c.c "moved" and an
incremental build of lib/libmd would fail with:
make: don't know how to make /usr/src/lib/libcrypt/../libmd/sha512c.c. Stop
Now this will just be seen as a stale dependency and cause a rebuild:
make: /usr/obj/usr/src/lib/libmd/.depend.sha512c.o, 13: ignoring stale .depend for /usr/src/lib/libcrypt/../libmd/sha512c.c
--- sha512c.o ---
...
This rebuild will only be done once since the .depend.sha512c.o will
be updated on the build with the -MF flags.
This also removes -MP being passed for the .depend.OBJ generation (which
would create fake targets for system headers) since the logic is no
longer needed to protect from missing files.

This may be used in later checks, such as in bsd.dep.mk, to
enable features that rely on the built-in value.
