[PATCH, rs6000] ELFv2 ABI 1/8: Add options and infrastructure

Hello, this is the first patch in the series to add support for the ELFv2 ABI. The ELFv2 ABI is the intended ABI for the new powerpc64le-linux port. However, it is not inherently tied to the byte order; it it possible in principle to use the ELFv2 ABI in big-endian mode too. Therefore, it is int
