Rename PowerPC64 pcrel GOT TLS relocations

These relocations should have had REL in their names, to reflect the
fact that they are pc-relative.  Fix that now by adding _PCREL.
I've added some back-compatibility code to support anyone using
.reloc with the old relocations.

include/
	* elf/ppc64.h (elf_ppc64_reloc_type): Rename
	R_PPC64_GOT_TLSGD34 to R_PPC64_GOT_TLSGD_PCREL34,
	R_PPC64_GOT_TLSLD34 to R_PPC64_GOT_TLSLD_PCREL34,
	R_PPC64_GOT_TPREL34 to R_PPC64_GOT_TPREL_PCREL34, and
	R_PPC64_GOT_DTPREL34 to R_PPC64_GOT_DTPREL_PCREL34.

	BFD_RELOC_PPC64_GOT_DTPREL34 to BFD_RELOC_PPC64_GOT_DTPREL_PCREL34.
