>Description:
	The Makefile has: PORTGCCVERSION=        ""
	which does the right thing for the post part, but can cause problems
	with, for example, 'make describe':

	/usr/ports/devel/msp430-libc (msp430-libc-gcc4-1.0.20110612) Error.
	BUILD_DEPENDS /usr/ports/devel/msp430-gcc"" -- dependency not found

>How-To-Repeat:
	See above
>Fix:
	The following patch fixes 'make describe' for me, but should be tested.
	Note, this is (somewhat annoyingly) different from how the equivalent
	in PLIST_SUB is handled, in part because of how make(1) parses its
	variables.
