Subject: [PATCH] Add a 'reproducible-tarball-dist' target

It's currently separate from the "tarball-dist" target
because it requires a tar implementation with mtree spec
support.

It's far from being perfect and does not enforce a
reproducible mode, but it's better than nothing.

After the git migration it can probably be removed anyway.
