allow the built-in operations to be redefined, at least not without
excessive force).
Instead, just disable LLVM's support for atomic operations for now.
Nothing in either clang or the tablegen tools currently depends on it.
This still allows users of head built before r198344 to upgrade to
top-of-head seamlessly.
emits calls for them, rather than expanding them inline. Older FreeBSD
versions compile for i386 by default and as such we end up with
unresolved symbols when we build LLVM's TableGen utility as a build
tool on them. Add the functions that GCC emits here, but don't bother
to make them atomic. Such is not needed.

This knob removes the tools that are exclusively used to view and
maintain the databases maintained by utmpx, namely last, users, who,
wtmpcvt, ac, lastlogin and utxrm.
The tool w is not in this list, because it has some other functionality
which is unrelated to utmpx; it is hardlinked to the uptime tool.
The WITHOUT_ACCT switch is supposed to omit tools related to process
accounting, namely accton and sa. ac(8) is just a simple tool that
prints statistics based on data in the utx.log database. It has nothing
to do with the former.
If WITH_BSD_GREP is not set, it will be 'bsdgrep' and GNUgrep will be
'[ef]grep'. Otherwise, BSD-grep will be the grep family, and GNUgrep
will be 'gnugrep'.

This is only partially regenerated, as the entries for FDT and GPIO seem to

Don't build clang bootstrap/build-tools depending on this flag. We also
keep gperf, devd and libstdc++ around to prevent foot-shooting and to
make this a two-way street.
A full featured groff is required during buildworld, so build it always
and don't rely on it being present on the host system.
vgrind(1) is tightly coupled to a roff processor and will not be
built/installed when groff is disabled. Also much of the roff'ed
documentation under share/doc will not be built/installed when
WITHOUT_GROFF is defined.

Deliverables: Small and clean code (1,4 KSLOC vs GNU's 8,5 KSLOC),
lower memory usage than GNU grep, GNU compatibility,
BSD license.
TODO: Performance is somewhat behind GNU grep but it is only
significant for bigger searches. The reason is complex, the
most important factor is that GNU grep uses lots of
optimizations to improve the speed of the regex library.
First, we need a modern regex library (practically by adopting
TRE), add support for GNU-style non-standard regexes and then
reevalute the performance issues and look for bottlenecks. In
the meantime, for those, who need better performance, it is
possible to build GNU grep by setting WITH_GNU_GREP.

Note that this is actually a no-op for most users, as this GNU
cpio was broken on -HEAD and 8-STABLE since last March until
the recent fix.
FreeBSD 8.0+ uses BSD cpio by default and the code is being
actively maintained.
