        * libc/include/sys/config.h (__IEEE_LITTLE_ENDIAN)
        (__IEEE_BIG_ENDIAN): Define appropriately for MIPS.
        Check that one of them is defined and error out if not.
        Add any platforms defined in <machine/ieeefp.h> that are missing.
        * libc/search/hash.h (DB_BYTE_ORDER, DB_BIG_ENDIAN)
        (DB_LITTLE_ENDIAN): New defines.
        * libc/search/hash.c: Replace all incorrect checks for
        _IEEE_LITTLE_ENDIAN with tests of BYTE_ORDER, and all uses of
        BYTE_ORDER, LITTLE_ENDIAN, and BIG_ENDIAN with DB_* versions.
        * libc/search/hash_page.c: Likewise.
