Bryan Drewery dfa099890c Add option UNIFIED_OBJDIR, on by default, which moves the default build OBJDIR.
This changes the build OBJDIR from the older style of /usr/obj/<srcdir> for
native builds, and /usr/obj/<target>.<target_arch>/<srcdir> for cross builds to
a new simpler format of /usr/obj/<srcdir>/<target>.<target_arch>.  This
new format is used regardless of cross or native build.  It allows
easier management of multiple source tree object directories.

The UNIFIED_OBJDIR option will be removed and its feature made permanent
for the 12.0 release.

Relnotes:	yes (don't note UNIFIED_OBJDIR option since it will be removed)
