An alternative approach would be to allow an empty hash in the hash file, e.g.
# From git => no hash
none xxx avrdude-eabe067c4527bc2eedc5db9288ef5cf1818ec720.tar.gz
This has the advantage that we don't have to revert this patch in the future
when we _do_ make reproducible tarballs (which is not rocket science, the
reproducible builds people in Debian and Fedora do it). Of course, we'll be
stuck with a s*tload of hash files that have this empty hash...
Regards,
Arnout
