Cool, that can't hurt and is also simpler to express in sed.

I tried to spike a generate-compiler-wrapper target into,
just to see if it'd work, but some of the juju in there is way beyond me. I
have a ways to go to catch up with your "make" skillz. :-)

Yeah, I circumrationalized this drawback too handily. I agree that we should
look at statistics from a slow machine before deciding to make pkgsrc work
this way.
