This is very cool! I've already added it to my devel version of
portmaster in several places. I call make a LOT in portmaster, so I
went through every invocation and added this wherever it worked (i.e.,
didn't cause a difference in (or absence of) output.
I'd also like to say thanks to Stephen, Alexander, and everyone else
who's taken an interest in optimizing the ports infrastructure. I've
managed to work around some of the inefficiencies with portmaster, but
I learn new tricks (like this one) on a regular basis. Having things
be more efficient to start with would be a great thing for all of our
users.

It depends on the target. My suggestion would be to test them on an
individual basis. It's usually pretty clear if they will work or not.
