77486630b1 R_PPC64_PCREL_OPT
The loads and stores handled in the second instruction of a sequence
marked by R_PPC64_PCREL_OPT may be a prefix instruction.  For example:
 pld ra,symbol@got@pcrel
0:
 pld rt,off(ra)
 .reloc 0b-8,R_PPC64_PCREL_OPT,(.-8)-(0b-8)
can be optimised to
 pld rt,symbol+off@pcrel
 pnop

	* elf64-ppc.c (xlate_pcrel_opt): Handle prefix loads and stores
	in second instruction.
	(ppc64_elf_relocate_section): Likewise.
