	R_PPC64_PLT_PCREL34_NOTOC, and R_PPC64_PLTSEQ_NOTOC.
	(ppc64_elf_check_relocs): Handle pcrel got and plt relocs.  Set

	(md_assemble): Warn for @pcrel on non-prefix insns.
	Accept @l, @h and @ha on prefix insns, and infer reloc without
	any @ suffix.  Translate powerxx relocs to suit DQ and DS field
	instructions.  Include operand tests as well as opcode test to
	translate BFD_RELOC_HI16_S to BFD_RELOC_PPC_16DX_HA.
	(ppc_fix_adjustable): Return false for pcrel GOT and PLT relocs.
	(md_apply_fix): Handle new powerxx relocs.
