The struct RawSockaddr contains a field Data which
should be uint8 on ppc64 and ppc64le, but is declared
as int8 in gccgo. This change adds a two new files
which contain the structure declaration for
RawSockaddr, one with the correct types for for ppc64
and ppc64le, and the other for non-ppc64 platforms.
