Add targets to generate distribution tarballs, and srpms, from a tree.
These will generate packages for whatever the current HEAD of the tree
is - if the HEAD is a release tag, then the packages will be named for
that release, if the HEAD is between releases, then git describe will
be used to create an appropriate version identifier.
The tarballs are generated from the current git repository contents,
anything not checked in will not be included.
