Modified files:
	cm3/m3-sys/m3cc/src/: m3makefile 

Log message:
	add support for omitting unnecessary m3cc builds during regression tests:
	
	If WORKSPACE is set in the environment and PREBUILT_CM3CG is set,
	this file is just used as the build result. No further checks are
	performed.
	
	This is of course a hack, but our current resources of build servers
	are heavily loaded by continually compiling the cm3cg backend, which
	is not necessary in most cases. We can detect via CVS when it _is_.
