On top of the IRIX 6 toplevel libgcc move, I noticed that IRIX doesn't
use crtfastmath.o yet. This patch corrects this, bootstrapped without
regressions on mips-sgi-irix6.5.
While doing this, I noticed that libgcc/config/mips/t-crtfm is identical
(modulo $(cpu_type)) to the generic libgcc/config/t-crtfm, so I've
changed the other mips targets that used it, too.
Ok for mainline?

gcc:
* config/mips/iris6.h (ENDFILE_SPEC): Use crtfastmath.o if
-ffast-math etc.
libgcc:
* config.host (mips-sgi-irix6.5*): Add t-crtfm to tmake_file.
Add crtfastmath.o to extra_parts.
(mips64*-*-linux*, mips*-*-linux*): Use t-crtfm instead of
mips/t-crtfm.
* config/mips/t-crtfm: Remove.
