Hmm...  I thought the whole point of having explicit configure targets
was to be able to run them in parallel.  Of course we'll still be able
to configure a sub-package while another builds, but that's not quite
as good.

We should definitely have a configure (or host-configure) target that
gets all packages to configure sequentially, such that those who want
to do parallel builds can still do them without having to do parallel
configures (i.e., run `make host-configure && make -j4 all/bootstrap´)
