PowerPC64 ld -q enhancements

[Alan Modra <amodra at bigpond dot net dot au>]

This patch adds some more --emit-relocs output on linker generated
PowerPC64 code.

bfd/
	* elf64-ppc.c (build_plt_stub): Add relocs on plt call stubs
	if emitrelocations.
	(get_relocs): New function, split out from..
	(ppc_build_one_stub): ..here.  Add relocs on plt_branch stubs if
	emitrelocations.  Remove indx temp.
	(ppc_size_one_stub): Count new stub relocs.
	(ppc64_elf_size_stubs): Count new glink reloc.
	(ppc64_elf_build_stubs): Emit glink reloc if emitrelocations.
	(ppc64_elf_finish_dynamic_sections): Output glink relocs.
	* elf32-ppc.c (ppc_elf_finish_dynamic_sections): Describe non-pic
	glink code.
ld/testsuite/
	* ld-powerpc/relbrlt.d: Update.  Also check .branch_lt section.
