Replace DT_PPC_TLSOPT with DT_PPC_OPT.
This removes the DT_PPC_TLSOPT/DT_PPC64_TLSOPT dynamic tag and replaces
it with DT_PPC_OPT/DT_PPC64_OPT tag to provide the same functionality
and more. This isn't backwards compatible, but the TLSOPT tag hasn't
been used since the tls optimisation support was never submitted to
glibc.
/include/elf/
* ppc.h (DT_PPC_TLSOPT): Delete.
(DT_PPC_OPT, PPC_OPT_TLS): Define.
* ppc64.h (DT_PPC64_TLSOPT): Delete.
(DT_PPC64_OPT, PPC64_OPT_TLS, PPC64_OPT_MULTI_TOC): Define.
bfd/
* 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.
binutils/
* readelf.c (get_ppc_dynamic_type): Replace PPC_TLSOPT with PPC_OPT.
(get_ppc64_dynamic_type): Replace PPC64_TLSOPT with PPC64_OPT.
