Hi!

While working on the “reproducible builds” effort [1], we have noticed
that rsync could not be built reproducibly.

The attached patch removes extra timestamps from the gzipped docs and
fixes the files mtime before building the binary packages. Once applied,
rsync can be built reproducibly in our current experimental framework.
