Makefile.libcompat: use one variable assignment per line

This makes it easier to carry or merge patches that remove gnu/
components.

Don't change directory owner to root when building with -DNO_ROOT

Currently the mtree calls in Makefile.inc1 all change the directory owner
to match the spec file. However, we should not be doing this during
distributeworld if -DNO_ROOT is passed. Additionally, when creating the
WORLDTMP directory hierachy there is no need to change the owner to root so
we now always pass the -W flag when populating WORLDTMP.

This is also required for building FreeBSD on Linux/Mac since the required
groups/users will not exist there which is how I discovered this issue.

Remove the various build flag hacks for GCC cross-compile.

The xtoolchain GCC packages have not required these flags since ports
commits r465416 and r466701. The in-tree GCC 4.2.1 has also been patched
in r335716 and r335717 to correctly honor --sysroot when looking for
includes and libraries.

lib32: Fix lib/libpmc/pmu-events files ending up in source directory.

This could happen with either WITHOUT_AUTO_OBJ=yes or MAKELEVEL>0 for
the initial 'make buildworld' command.

This now ensures that build-tools targets have 'make obj' ran if needed.

This is especially problematic for pmu-events since it is not directly
connected in the build. Normally the 'make includes' call right before
this implicitly creates the objdir with a 'make obj' already but
misses pmu-events because it is disconnected from lib/libpmc. Fixing that
would make this new 'make obj' pointless but it is being added to avoid
this problem in the future should another tool be connected like this.

Fix nested MAKEOBJDIRPREFIX breaking various release/buildworld/toolchain targets.

This problem was caused by r325329 and r325350.

For the release(7) targets, some will run mm-mtree.sh which itself runs make
with a MAKEOBJDIRPREFIX. The execution of that script leaks OBJROOT,
MAKEOBJDIR, and MAKELEVEL=1 in the environment. This causes the mm-mtree makes
to not do some basic setup of OBJROOT and only use this special
MAKEOBJDIRPREFIX case which fails to empty out MAKEOBJDIRPREFIX for further
nested makes, such as a tree walk. If that tree walk sets OBJROOT/OBJTOP such
as r325329 is doing, then the wrong OBJDIRs end up being used due to the
unemptied MAKEOBJDIRPREFIX being preferred over the proper MAKEOBJDIR.

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)
