Terry, we only support building the world (ie, anything in /usr/src) with
the *SYSTEM* compiler. If you are wanting to do:
cd /usr/src
make CC=FOOcc CXX=FOO++ buildworld
Then you are going off into the "not-supported woods" and you should
expect to have to do some hacking.
If you are wanting to use /usr/share/mk for your own projects, then that
is also a debatable issue. Some claim /usr/share/mk is only for use of
/usr/src; others feel it should be generic and truely usable for other
code. If you have some well tested patches to fix the assumptions in
/usr/share/mk, we might can change things.
