Also, it doesn't even list those directories in the Makefile, so we
don't waste time checking - repeatedly - to see if they're configured.

More accurately, it can configure one module while it starts building
another.  We can't actually do two configures at the same time because
of the shared cache.

Yup.  It should at least be "cd foo && make" not "cd foo; make", but a
make:configure dependency might be missing too.  Nate?

Nate's working on a fix to cover all of them.  After that, we can
worry about missed ones.
