* mips.sc-sh: New file. Ultrix, and hopefully other MIPS ECOFF targets, linker script. * mipslit.sh: New file. Little endian MIPS emulation. * config/mips-lit.mt: New file. Use mipslit emulation. * configure.in (mips-dec-ultrix*): Use target mips-lit. * Makefile.in (ALL_EMULATIONS): Added em_mipslit.o. (em_mipslit.c): New target. Uses mipslit.sh.
