[m-dev.] diff: fix *.gc.par build problem

[Fergus Henderson]

Estimated hours taken: 0.5

Mmake.common.in:
	Turn off ERROR_UNDEFINED for .gc.par grades, since
	(a) currently we get link errors when building the Mercury
	shared libraries in those grades, because the thread-safe
	version of the Boehm GC needs to be linked with some
	fairly system-specific libraries
	(b) it's easier and safer to just turn it off here than to
	try to explicitly link with all the necessary libraries
	in that case.
