Hi,

I applied the patch below to SVN-trunk. We've been using it for the 
RTEMS toolchains for several months.

	* config/lm32/t-rtems: New.
	* config.gcc (lm32-*-rtems*): Add t-rtems.

just a nit: why three lines where a single one would be clearer?

Keeping the impact of GCC changes low / Keeping the rtems parts separate 
from "generic GCC" parts.

Admitted, we could use a common line for t-rtems and lm32/t-rtems.
