Bug#877384: rcs: please make the build reproducible

[Chris Lamb]

Source: rcs
Version: 5.9.4-3
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that rcs could not be built reproducibly as it writes the build
date into the generated manpages.

Patch attached.
