BFD64_LIBS, make the latter depending on the availability of BFD64. Add archive64.c source file. * archive64.c: New file implementing bfd_elf64_archive_slurp_armap and bfd_elf64_archive_write_armap, code from elf64-mips.c * archive.c (bfd_slurp_armap): Add ELF64 archive support. * config.bfd (mips*-*-irix6*): Allow with BFD64 only. (mips64*el-*-linux*): Likewise. (mips*el-*-linux*): Likewise. Reorder entries. * configure.in (bfd_libs): Define in dependency of BFD64 and AC_SUBST it. * elf64-mips.c (mips_elf64_slurp_armap): Remove, use bfd_elf64_archive_slurp_armap instead. (mips_elf64_write_armap): Remove, use bfd_elf64_archive_write_armap instead.
