modula2: tidyup makeSystem

This patch provides a tidyup for gcc/m2/tools-src/makeSystem.
It only runs the compiler once and will echo a debug command line
should it fail.

gcc/m2/ChangeLog:

	* tools-src/makeSystem: Invoke ${COMPILER} once and adjust
	the echo string to expand the shell variables with -wrapper
	gdb, --args.
