Apply changes from mainline to 2.24
2013-10-30 Alan Modra <amodra@gmail.com>
* elf32-ppc.c (ppc_elf_size_dynamic_sections): Use new DT_PPC_OPT
tag to specify tls optimisation.
* elf64-ppc.c (ppc64_elf_size_dynamic_sections): Likewise.
(ppc64_elf_finish_dynamic_sections): Specify whether multiple
toc pointers are used via DT_PPC64_OPT.
