Add two utilties for listing and stashing away package files obtained

from recursive dependency builds a la:

  make DEPENDS_TARGET='install package clean' all install package clean

The pkg-list script obtains a list of the packages in the dependency
directories; the pkg-stash script moves them away to a predefined
directory, adding a timestamp to the package file name.  This is
convenient for keeping ready-built packages for system rescue
activities.
