Subject: libm: Add feenableexcept and fedisableexcept to library on powerpc

Summary:
These functions are missing from the library itself, and exist solely in
the header.  This breaks a few ports that expect libm to have the
symbols in the library itself.

Questions on MFC-ability: Can this be MFC'd to 13.2, and how?
