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? Reviewers: imp, emaste, kib Reviewed By: kib Differential Revision: https://reviews.freebsd.org/D35204
