_SKIP_BUILD will be set when nothing is expected to be built. This can
be used to optimize some tree-walks and operations which don't need to
load dependency files or generate dependencies via beforebuild-style
hacks.

This was a mistake in r295641, but is effectively prevented from
being a problem due to r296699 preventing 'make all' from being
usable at MAKELEVEL 0 for DIRDEPS_BUILD.

- 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
without filemon loaded.
- Move the error into Makefile and only apply it when building
from the META_TGT_WHITELIST target list.
-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
phase [1].

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

to use ``.if defined()'' inside bsd.own.mk to test for defines
in individual makefiles. For example, setting DEBUG_FLAGS in
Makefile didn't take the desired effect on the STRIP assignment.
Added bsd.init.mk (like in NetBSD) that handles the inclusion
of ../Makefile.inc and bsd.own.mk from all bsd.*.mk files that
"build something".
Back out bsd.own.mk,v 1.15: moved OBJFORMAT initialization back
to sys.mk (several source tree makefiles want to check it early)
and removed MACHINE_ARCH initialization (it's hard to see from
looking at the commitlogs what the problem was at the time, but
now it serves no purpose).
Prohibit the direct inclusion of bsd.man.mk and bsd.libnames.mk.
Protect bsd.obj.mk from repetitive inclusion. Prohibiting the
direct inclusion of bsd.obj.mk might be a good idea too.
