Latest musl release supports ppc64 architecture (both big endian and little endian), so this commit adds support for this. Since musl implements the ELFv2 ABI for both big-endian and little-endian PowerPC64, we have to force using this ABI on PowerPC64 big endian (normally elfv1 is the default). Also, only gcc 6.x has the necessary changes to support musl on PowerPC 64, so we restrict the gcc version selection accordingly. Tested with Qemu for big endian and little endian configurations.
