r316647 corrected the build of tblgen and libllvm as dependencies for
LLD so undo the temporary seat-belt.
We still want to extend the build infrastructure to automatically detect
the case where the host LLD can be used instead of building a bootstrap
LLD, and likely extend libllvmminimal to meet LLD's needs for cases
where the build includes LLD but not Clang.

When this option is enabled, only gdb and kgdb are installed to
/usr/libexec for use by crashinfo(8). Other bits of GDB such as
gdbserver and gdbtui are not installed. For this option to be
effective, GDB must be enabled.
Rework r317094 to re-enable GDB on all platforms but enable
GDB_LIBEXEC on platforms for which the GDB in ports is a superset of
functionality.

The GNU extension bits in the base system are old, no longer faithful
to upstream, and surprising in some regards. Switch to documenting
WITH_GNU_GREP_COMPAT and default GNU_GREP_COMPAT to OFF in the name of
good behavior.
According to http://www.regular-expressions.info, GNU extensions:
- Add missing quantifiers to BREs: \?, \+
- Add branching to BREs: \|
- Add backreferences (\1 through \9) to EREs
- Add \w, \W, \s, and \S corresponding to :alnum:, [^[:alnum:]],
:space:, and [^[:space:]] respectively
- Add word boundaries and anchors:
\b: word boundary
\B: not word boundary
\<: Strt of word
\>: End of word
\`: Start of subject string
\': End of subject string
These extensions are still available in /usr/bin/grep by default today,
as it is still GNU grep. As part of the bsdgrep migration plan these
extensions may be added to bsdgrep's regex support if necessary.

Bugs have been found in the fastmatch implementation as used in bsdgrep.
Some have been fixed (r316495) while fixes for others are in review
(D10098).
In comparison with the fastmatch implementation, Kyle Evans found that:
- regex(3)'s performance with literal expressions offers a speed
improvement over fastmatch
- regex(3)'s performance, both with simple BREs and EREs, seems to be
comparable
The regex implementation was imported in r226035, and the commit message
reports:
This is a temporary solution until the whole regex library is
not replaced so that BSD grep development can continue and the
backported code gets some review and testing. This change only
improves scalability slightly, there is no big performance boost
yet but several minor bugs have been found and fixed.
Introduce a WITH_/WITHOUT_BSD_GREP_FASTMATCH knob to support testing
of both approaches.

If WITH_LLD is disabled LLD is not built and cannot be installed as
/usr/bin/ld, so disable WITH_LLD_IS_LD.
Currently we do not compare the LLD host/in-tree version and LLD
requires the LLVM libraries to be built, so force WITH_SYSTEM_COMPILER
off when WITH_LLD_IS_LD is set.
The logic for bootstrapping LLD requires some tidying later. We should
be able to detect that the host linker is the same version and avoid
building LLD in the same way that WITH_SYSTEM_COMPILER handles Clang.
We also may be able to extend libllvmminimal to meet LLD's needs. For
now this change unbreaks buildworld with default settings except for
WITH_LLD_IS_LD.

Recent versions of Clang are becoming usable for non-x86 non-arm FreeBSD

- This was broken by r300350 and r300885.
- Add some comments around the external GCC logic since it is spread out
and in need of some cleanup.
- The problem was that X_COMPILER_TYPE is always defined from CC->XCC's
default, so if /usr/bin/cc is GCC (as it is on native powerpc64) then
X_COMPILER_TYPE was getting GCC and triggering the external logic in
Makefile.libcompat. It was intended to always provide -isystem with
GCC since --sysroot is used into the lib32 sysroot which won't modify
the header path without the -isystem. The use of the libc++/std=c++11
override was only intended to be used for external compilers though
(more accurately GCC 4.8+ but that's a separate assumption to
cleanup). Apply the same logic from Makefile.inc1 to Makefile.libcompat
to only add the libc++ override when needed for external compilers.

The WITH_META_MODE build is intended to be a working incremental build.
It spies on the build command to see if things should be rebuilt if the
command changes. If you run buildworld, it builds a cross-compiler,
then do installworld and buildworld again it will invoke the
WITH_SYSTEM_COMPILER logic. This then adds on -target/--sysroot, etc,
and causes rebuilds due to the changed build command even though the
compiler used is technically the same revision. Since the incremental
build is not cleaning anything by default then there is much
less risk to rebuilding the already-existing cross-compiler. Just
disable the combined logic and always use and build the cross-compiler.
An alternative to this would be to always pass -target/--sysroot. Doing
so may occur in the future.
