[janitor] mips-tfile.c and mips-tdump.c

[Aldy Hernandez]

AFAICT these files are only used in:

	alpha*-dec-osf[45]*)

for...

         if test x$gas != xyes
         then
                 extra_passes="mips-tfile mips-tdump"
         fi

Is this still a used/supported target, and/or configuration?
