11.0 -r303168 for TARGET_ARCH=powerpc: etc/mtree/BSD.lib32.dist usr/lib32/i18n/ usr/lib32/dtrace/ usr/lib32/ involved

Context: amd64 11.0 -r303168 cross build sequence WITH_META_MODE=yes of TARGET_ARCH=powerpc (non-64), buildworld then installworld and mergemaster to a local directory:

mergemaster produced . . .

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.)
