Me neither. Historically, make source was meant to ensure that
everything is downloaded now so you could go offline and continue
building _ON_THE_SAME_MACHINE_. This potentially does indeed break down
if you try to reuse the download directory on another machine, but I
don't quite see how we can solve this for all situations.
