* configure.in: Add entry for mips-*-sysv4*MP*
        * configure: Rebuild
        * config/tc-mips.c (mips_target_format): Return elf32-tradbigmips or
        elf32-tradlittlemips for traditional mips targets.
        * config/tc-mips.c (md_estimate_size_before_relax): Duplicate the
        test for Link Once sections as in adjust_reloc_syms.
        * config/te-tmips.h: New file for traditional mips targets. Define
        TE_TMIPS.
