e5074fa18e Renaming libifc to libifconfig in response to feedback on initial commit of
this library. Sticking to 'libifconfig' (and 'ifconfig_' as function prefix)
should reduce chances of namespace collisions, make it more clear what the
library does, and be more in line with existing libraries.

- DIRDEPS_BUILD: Fix crunchgen builds losing their library dependencies
  on a nop-rebuild.
- META_MODE: Fix not rebuilding various crunch.mk targets if their .meta
  files warrant a rebuild.  They were lacking .meta files previously.
  This adds .NOMETA to the crunch objects being used since they are
  already built.  Bmake was forcing a rebuild on them since their
  .meta files were not in the expected place; there is no reason to
  rebuild them.

5ac77e13d9 FAST_DEPEND/META_MODE: Fix several issues with SRCS containing '/'.
- For FAST_DEPEND, properly apply the -M flags when compiling by
  enduring that the condition also has the s,/,_,g filter applied to it
  first.
- For FAST_DEPEND, properly read from the filtered filename.
- For META_MODE, it needs to read from a full-pathed and s,/,_,g replaced
  filename based on bmake's meta_name() function which names the .meta
  file for SRCS with '/' in them.

This support has not been extended to the kernel build yet but may be in the

a5e10af8bc Add libifc, a library implementing core functionality that exists in ifconfig(8) today.
libifc (pronounced lib-ifconfig) aims to be a light abstraction layer between
programs and the kernel APIs for managing the network configuration.
This should hopefully make programs easier to maintain, and reduce code
duplication.

Work will begin on making ifconfig(8) use this library in the near future.

This code is still evolving. The interface should not be considered stable until
it is announced as such.

7782c2dc96 FAST_DEPEND: Fix 'make all install' not properly rebuilding based on .depend.* files.
An optimization is in place to skip reading the .depend.* files with
'make install'.  This was too strong and broke 'make all install' and
'make foo.o foo install'.  Now only skip reading the dependency files
if all make targets ran are install targets.

The problem comes about because headers are only added in as a guessed
dependency if .depend.* files do not yet exist.  If they do exist, even
if being skipped from being read, then the header dependencies are not
applied.  This applies to all #included files, and not just headers.

adb3ac2dae For 'make <directory>' hook into the all_subdir_<directory> targets.
This fixes parallel build issues when trying to depend on ${SUBDIR}.  An
example of this in share/i18n/csmapper/Makefile where mapper.dir depends
on ${SUBDIR} having been traversed and built already.  Before this
change running make in that directory would build the subdirectories
twice.  This led to obscure build races.  While reworking that build
may be possible, the framework should not so easily allow creating such
problems.

Now depending on <directory> will properly redirect to the
all_subdir_<directory> target rather than invoking the inline shell.

This also makes 'make -jX <directory>' now respect any
SUBDIR_DEPEND_<directory> statements when SUBDIR_PARALLEL is defined.
This is not entirely intended and may be changed later.

46aba11fa0 Stop using _SUBDIR internally for non-SUBDIR_PARALLEL builds.
This is unifying more of the logic.  Rather than create targets such
as 'all: all_subdir_foo' when using SUBDIR_PARALLEL and using
'all: _SUBDIR' when not using SUBDIR_PARALLEL, always use the
expanded out <target>_subdir_<directory> pattern.  When not using
SUBDIR_PARALLEL, have each directory-target depend on the previously
defined targets as to respect the *order* of SUBDIR.

Using 'make -N' now prints all directory traversals individually rather
than using a loop, since a loop is no longer used to traverse.

This is part of an effort to cleanup handling of some edge cases
involving 'make <directory>' and making it simpler in the sense
that the pattern used to build is the same for all modes.

2c03309f28 Remove ${OBJDUMP} as it is not used by the base system
It was added to sys.mk relatively recently (r274503) for EFI builds
but is no longer used by the base system. The in-tree binutils are
outdated, will not be updated, and will be removed in the future.
Remove it from the toolchain build now to slightly simplify the build
and make sure we don't grow an accidental dependency.

Note that this affects only the toolchain build, and does not affect
/usr/bin/objdump in the built world.

42d9d45fb8 Fix native powerpc64 build of lib32 with in-tree GCC.
- 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.

- Move the sys.mk filemon requirement to bsd.init.mk as a warning.
  This is intended only to show when building directly in a subdirectory

- Move the error into Makefile and only apply it when building

-DNO_FILEMON can be used to suppress both the warning and the error but
makes WITH_META_MODE less useful.  It will only compare build commands
in this mode rather than track all dependencies.

This fixes installing from a jail which doesn't need filemon in this
