BTW, the MIPS has been using this since:

Wed Jun  7 18:27:51 2000  Andrew Cagney  <cagney@b1.cygnus.com>

        * configure.in (DEFAULT_BFD_ARCH, DEFAULT_BFD_VEC): Use config.bfd
        to determine the default architecture / target.
        * acconfig (DEFAULT_BFD_ARCH, DEFAULT_BFD_VEC): Add.
        * configure, config.in: Regenerate.
        
        * arch-utils.c (set_endian): Better separate multi-arch and non-
        multi-arch cases.
        (set_endian_from_file): Call internal_error when multi-arch.
        (initialize_current_architecture): Rewrite logic selecting a byte
        order.  Use DEFAULT_BFD_ARCH DEFAULT_BFD_VEC.
        (version.h): Include.

        * config/mips/tm-mips.h, config/mips/tm-bigmips64.h,
        config/mips/tm-bigmips.h: Delete definition of
        TARGET_BYTE_ORDER_DEFAULT.
