Reading the doc pages for automake, it looks like automake should not
install *anything* if either prefix or exec_prefix is the empty string,
under any circumstances.

So if one was trying to effect some interesting local policy described

   make install exec_prefix=/ DESTDIR=/tmp/dest


   make install prefix=/ DESTDIR=/tmp/dest

would be the way to do that, right?
