[PATCH] Fix mips-tfile.c compilation warnings

No, ironically mips-irix6 doesn't use "mips"-tfile whereas apparently
alpha does.  I've never figured out why this is, but I am curious. :-)

If -Werror is the only thing stopping your bootstrap, you can test
your patch by configuring with --disable-werror, and test with and
without the patch to see if something breaks.
