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

patm(4) devices.
Maintaining an address family and framework has real costs when we make
infrastructure improvements. In the case of NATM we support no devices
manufactured in the last 20 years and some will not even work in modern
motherboards (some newer devices that patm(4) could be updated to
support apparently exist, but we do not currently have support).
With this change, support remains for some netgraph modules that don't
require NATM support code. It is unclear if all these should remain,
though ng_atmllc certainly stands alone.
Note well: FreeBSD 11 supports NATM and will continue to do so until at
least September 30, 2021. Improvements to the code in FreeBSD 11 are
certainly welcome.

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.

These have no effect (and WITHOUT_GNU is documented as having no
effect). I intend to later introduce a WITHOUT_GPL knob to serve a
similar purpose as WITHOUT_GNU's previously documented intent, but with
a more accurate name. To avoid confusion over the transition though just
remove the existing, nonfunctional ones.
Note that this commit also adds the default riscv settings for all
options since riscv was added to 'make targets' since the last time
this was generated.

GDB in ports contains all of the functionality as GDB in base
(including kgdb) for these platforms along with additional
functionality. In-tree GDB remains enabled on ARM and sparc64.
GDB in ports does not currently support kernel debugging on arm,
and ports GDB for sparc64 has not been tested (though it does
include sparc64 support).

Specifically, set '-mabi=XX' in AFLAGS, CFLAGS, and LDFLAGS. This permits
building MIPS worlds and binaries with a toolchain whose default output
does not match the desired TARGET_ARCH.
_LDFLAGS (which is used with LD instead of with CC) required an update as
LD does not accept the -mabi flags (so they must be stripped from LDFLAGS
when generating _LDFLAGS). For bare uses of LD (rather than linking via
CC), the desired ABI must be set by setting an explicit linker emulation
as done in r316514 for kernels and kernel modules.

In a cross-build, the build-tools are native host binaries. We do not
want to rebuild them when building for the target. Bmake previously
did not support checking .NOMETA on an existing target, so .NOMETA_CMP
was used here. However, .NOMETA_CMP still triggers meta mode conditions
if the number of commands or the command changes. In r312467 the paths
to build ncurses files were modified and thus triggered meta mode to
rebuild the build tools (make_keys, make_hash) in ncurses during the
target build. Bmake 20160604 committed in r301462 changed .NOMETA to
also skip meta mode logic for an existing .meta file as well, thus it
is now the proper fix here.
I explored moving the build-tools output to WORLDTMP/tools with
relatively good success, but have concerns that doing so would be
problematic for downstream vendors who use LOCAL_TOOL_DIRS and
expect the tools to be in current OBJDIR for the target. It also
adds more complexity into finding the tools during target build
and handling of where they are for rescue/rescue and
mkcsmapper_static/mkesdb_static which should really not be connected in
build-tools anyway.
