	How about having a 'NOBUILD' variable in /etc/mk.conf, which
	could be set to a space separated list of programs, then 
	bsd.prog.mk would do nothing if PROG was in that list.

	Sounds like it might scale very nicely :)

	I've just hacked up an implemention - its possibly not for the
	weak of stomach, but it seems to work. Diffs from bsd.prog.mk
	below. If anyone could give me hints on how to tidy it up I'd
	be greatful :)
