Between 2 and 3 I think I actually like 3 better. It seems general
enough to eliminate all ill-effects of the overly generic %.out: %
rule. And it's very simple (at least in my tests it was):
	touch $@

Another possibility might be to enable the %.out: % rule only for
examples and disable it for tests and everything else work? We don't
need to create .out files anywhere else, do we?
