64-bit MIPS ELF ABI objdump support:
* elf64-mips.c: New file. * Makefile.in: Rebuild dependencies. (BFD64_BACKENDS): Add elf64-mips.o. (BFD64_BACKENDS_CFILES): Add elf64-mips.c. * config.bfd (mips*el-*-elf*) Add bfd_elf64_bigmips_vec and bfd_elf64_littlemips_vec to targ_selvecs. (mips*-*-elf*): Likewise. * confingure.in: Add bfd_elf64_bigmips_vec and bfd_elf64_littlemips_vec to vector switch. * configure: Rebuild. * elf32-mips.c (_bfd_mips_elf_section_from_shdr): New function, broken out of mips_elf_section_from_shdr. (mips_elf32_section_from_shdr): Rename from mips_elf_section_from_shdr. Call new function. (elf_backend_section_from_shdr): Update name of renamed function. * elf-bfd.h (struct elf_size_info): Change second parameter of write_out_phdrs to be const. Likewise for second parameter of swap_symbol_out. (struct bfd_elf_section_data): Add rel_hdr2 field. (bfd_elf32_swap_symbol_in): Change second parameter to be const.

If there is already a reloc section for the section, add the new one to rel_hdr2. Increment reloc_count rather than setting it. * elfcode.h (elf_slurp_symbol_table): Define name as macro. Remove static declaration. (elf_write_shdrs_and_ehdr): Define name as macro. (elf_write_out_phdrs): Likewise. (elf_swap_ehdr_in, elf_swap_ehdr_out): Declare.
