PATCH: correctly handle no-gc case

[Tom Tromey]

I'm checking in the appended patch.  It changes gcj to correctly
handle the case where no GC library is used.  It also cleans up space
allocation for the arguments.

1998-11-12  Tom Tromey  <tromey@cygnus.com>

	* jvspec.c (lang_specific_driver): Correctly handle case where
	GC_NAME not defined.
