PowerPC64 ELFv2 support for gold.
elfcpp/
* powerpc.h (EF_PPC64_ABI): New enum constant.
(STO_PPC64_LOCAL_BIT, STO_PPC64_LOCAL_MASK): Likewise.
(ppc64_decode_local_entry): New function.
(ppc64_encode_local_entry): Likewise.
gold/
* powerpc.cc (Powerpc_relobj::abiversion, set_abiversion,
ppc64_local_entry_offset, ppc64_local_entry_offset,
do_read_symbols): New functions.
(Powerpc_relobj::e_flags_, st_other_): New vars.
(Powerpc_relobj::Powerpc_relobj): Call set_abiversion.
(Powerpc_dynobj::abiversion, set_abiversion): New functions.
(Powerpc_relobj::e_flags_): New var.
