Hi!

While conducting a research in the spirit of the "reproducible builds" [1], we have noticed that the package "dd_rescue" could not be built reproducibly, in that the gzip command is invoked without -n.

The attached patch removes timestamps when creating the archive. Once applied, the package can be built reproducibly.


Additional info:
* dd_rescue 1.99.11-1

Steps to reproduce:
The unreproducible build result could be detected with reprotest [2].

I've applied the patch; However, I think this might be worth going to upstream with rather than discussing with downstream maintainers.

Thanks!
