mips-rtems support

mips-rtems support

Hi,

The MIPS libffi support assumes that the target
has sgidefs.h.  Per Ian's suggestion, this patch
adds the few constants required from that file
on mips-rtems since we do not have it.

Can this please be applied and merged to gcc?

Thanks.

         * configure.ac: Add mips*-*-rtems* support.
         * configure: Regenerate.
         * src/mips/ffitarget.h: Ensure needed constants are available
         for targets which do not have sgidefs.h.

Both m68k and mips changes are now committed
to the gcc libffi source.

I will close the two m68k libffi PRs.

Thanks.
