make syntax-check is definitely wrong about these.  We must not use
$(VG) here since it will cause VG to be expanded at the wrong place.

This is also wrong because RHEL 5 (which is what these rules target)
didn't support the $(..) syntax.

Sorry, but make syntax-check is largely broken, or at least advisory.

Maybe it's better to remove it if it doesn't do anything useful?
