[csl-am] missing SIGTRAP

It appears that the builtin simulators use host signal numbers to communicate 
with gdb. This causes problems on windows hosts because SIGTRAP isn't 
defined. The attached patch provides a definition for SIGTRAP if the host 
doesn't have one. This probably isn't the "right way" to fix this, but it's 
near enough for our purposes.

Applied to csl-arm-20050325-branch.

	* gdb/remote-sim.c (SIGTRAP): Provide default defnition.
	* gdb/signals/signals.c (SIGRAP): Ditto.
