Consolidate ppc64 ld/bfd communication
Moves assorted variables used to communicate between ld and bfd into a struct, hooks it into the bfd link_hash_table early, and removes all other places where such variables were passed piecemeal. bfd/ * elf64-ppc.h (struct ppc64_elf_params): Define. (ppc64_elf_init_stub_bfd, ppc64_elf_edit_opd, ppc64_elf_tls_setup, ppc64_elf_setup_section_lists, ppc64_elf_size_stubs, ppc64_elf_build_stubs): Update prototype. * elf64-ppp.c (struct ppc_link_hash_table): Add params, delete other fields now in params. Adjust code throughout file. (ppc64_elf_init_stub_bfd): Delete "abfd" parameter, add "params". Save params pointer in htab. (ppc64_elf_edit_opd, ppc64_elf_tls_setup, ppc64_elf_setup_section_lists, ppc64_elf_size_stubs, ppc64_elf_build_stubs): Remove parameters now in "params". ld/ * emultemps/ppc64elf.em (params): New static struct replacing various other static vars. Adjust code throughout file.
