[rkward] /: Debian build: Make build reproducible

[Thomas Friedrichsmeier]

Git commit 2bd7f0454a20e6e64844153df69f59d1a1b79847 by Thomas Friedrichsmeier.
Committed on 29/11/2015 at 19:50.
Pushed by tfry into branch 'master'.

Debian build: Make build reproducible

Summary: Diff taken from https://bugs.debian.org/783290 for testing purposes.

Test Plan: The idea itself is acceptable, of course, but, importantly, needs to support building without specified build-timestamp (need to adjust rkpackage_install.cmake.in, only, I think).
