* elf64-ppc.c (CROR_151515, CROR_313131): Define.

	(ppc64_elf_relocate_section): Use them.  Don't look for plt calls
	on R_PPC64_ADDR24 relocs.  Require a nop or no link reg on plt
	call branches.  Correct undefined weak destination.
	(ppc64_elf_func_desc_adjust): Always create at least one blr in
	.sfpr, and correct case where either only savef* or restf* is
	needed.

	Long branch stubs, multiple stub sections.
	* elf64-ppc.h (ppc64_elf_setup_section_lists): Declare.
	(ppc64_elf_next_input_section): Declare.

	(create_linkage_sections): Use bfd_make_section_anyway.  Create
	.branch_lt and .rela.branch_lt sections.  Don't create .stub.
	(ppc64_elf_check_relocs): Set has_14bit_branch on R_PPC64_REL14*,
	and set up for plt call stubs.  Link func and func desc syms.
	(ppc64_elf_gc_sweep_hook): Handle REL14* as per REL24.
	(func_desc_adjust): Avoid hash lookup when func desc sym available
	via shortcut, and set links when processing.
