 Actually, the "do nothing under dependall, do everything under release" part
 can't easily be avoided; because distrib/ isn't self-contained. It depends
 on 'dependall' having being run over the whole tree to work.
 
 I'm not sure why MAKEVERBOSE=1 doens't work; the commands do show up in my
 make log even without MAKEVERBOSE=1.
