* elf64-ppc.c (ppc64_elf_func_desc_adjust): Don't allow _savef* and
_restf* to be satisfied by shared libs, and always force them local.
(toc_adjusting_stub_needed): Avoid scanning linker created sections.
Correct test for "bl".
(ppc64_elf_relocate_section <R_PPC64_TLS>): Correct test for
primary opcode 31.
