Log message:
	bfd/
	* elf64-ppc.c: Define more insns used in plt call stubs.
	(ppc64_elf_brtaken_reloc): Assume isa version 2 or above.
	(ppc64_elf_relocate_section): Likewise.
	(enum ppc_stub_type): Add ppc_stub_plt_call_r2save.
	(struct ppc_link_hash_table): Increase size of stub_count array.
	Add plt_stub_align and plt_thread_safe.
	(ALWAYS_USE_FAKE_DEP, ALWAYS_EMIT_R2SAVE): Define.
	(plt_stub_size, plt_stub_pad): New functions.
	(build_plt_stub): Emit barriers for power7 thread safety.  Don't
	emit needless save of r2.
	(build_tls_get_addr_stub): Adjust params.
	(ppc_build_one_stub): Handle ppc_stub_plt_call_r2save and aligning
	plt stubs.  Adjust build_*plt_stub calls.
	(ppc_size_one_stub): Similarly.
	(ppc64_elf_size_stubs): Accept plt_thread_safe and plt_stub_align
	params.  Choose default for plt_thread_safe based on existence of
	calls to thread creation functions.  Modify plt_call to
	plt_call_r2save when no tocsave reloc found.  Align tail of stub
	sections.
	(ppc64_elf_build_stubs): Align tail of stub sections.  Adjust
	output of stub statistics.
	(ppc64_elf_relocate_section): Handle ppc_stub_plt_call_r2save.
	* elf64-ppc.h (ppc64_elf_size_stubs): Update prototype.
	ld/
	* emultempl/ppc64elf.em (PARSE_AND_LIST_PROLOGUE,
	PARSE_AND_LIST_LONGOPTS, PARSE_AND_LIST_OPTIONS,
	PARSE_AND_LIST_ARGS_CASES): Handle --{no-,}plt-thread-safe and
	--{no-,}plt-align.
	(plt_thread_safe, plt_stub_align): New vars.
	(gld${EMULATION_NAME}_after_allocation): Pass them to
	ppc64_elf_size_stubs.  Align stub sections according to plt_stub_align.
	* ld.texinfo: Document new command line options, and an old
	undocumented option.
