For some reason "lib32" is involved a little bit when no such is needed.

Side note:
WARNING to avoid bad implications: clang 3.8.0 produces code that violates the
powerpc (32-bit) ABI FreeBSD requires relative to stack handling. There are
other problems as well, such as exception handling. To actually use the
buildworld result I'd use a kernel modified to have a so-called "red-zone" for
signal delivery. clang can not yet build the kernel so that part would be gcc
4.2.1 based. This does not deal with the exception handling issues or other
things but can be fairly useful. (I'm weeks away from having powerpc or
powerpc64 access again.)
