[m-rev.] diff: skip boehm_gc for grades which won't use it

boehm_gc/Mmakefile:
	Don't build the Boehm collector in grades which won't use it,
	e.g. `--gc none' or `--gc accurate' grades.  Previously we
	were avoiding building it for the IL and Java backends,
	but we should do the same for C backend grades which don't
	use the Boehm collector.
