Subject: [PATCH 2/2] Don't pass -m32/-m64 where it's not supported.

Only PowerPC, SPARC, and x86 do support the -m32 and -m64 compiler options [1].

Rather then excluding all architectures not supporting these options as it is
done in commit c0634341d9ee2c02d3a55c91dafb988afc066c49 [2], include all
architectures that do support them.

This will fix building Boost for the SuperH architecture with Buildroot [3].
