PowerPC64 tls_get_addr_desc static support
This provides a linker generated __tls_get_addr_desc wrapper function
preserving registers around a __tls_get_addr call. The idea being to
support __tls_get_addr_desc without requiring a glibc update.
bfd/
* elf64-ppc.c (struct ppc_link_hash_table): Add tga_group.
(ppc64_elf_archive_symbol_lookup): Extract __tls_get_addr_opt for
__tls_get_addr_desc.
(ppc64_elf_size_stubs): Add section for linker generated
__tls_get_addr_desc wrapper function. Loop at least once if
generating this function.
(emit_tga_desc, emit_tga_desc_eh_frame): New functions.
(ppc64_elf_build_stubs): Generate __tls_get_addr_desc.
