Fix powerpc64 -r --save-restore-funcs

[Alan Modra <amodra at gmail dot com>]

It looks like --save-restore-funcs with -r has never worked, due to
sfpr section not being created when relocatable.

	* elf64-ppc.c (create_linkage_sections): Create sfpr when
	save_restore_funcs, rest of sections when not relocatable.
	(ppc64_elf_init_stub_bfd): Always call create_linkage_sections.
	(sfpr_define): Define all symbols on emitted code.
	(ppc64_elf_func_desc_adjust): Adjust for sfpr now being created
	when relocatable.  Move sfpr_define loop earlier.
