Hi!

While working on the “reproducible builds” effort [1], we have noticed
that wordwarvi could not be built reproducibly, by design, exposing one of the 
very very few useful uses of capturing the build time (I have seen) :)

quoting from 
https://sources.debian.net/src/wordwarvi/1.00%2Bdfsg1-3/wordwarvi.c/#L9947

	/*
	 * A little joke for the programmers.  If *you* built it
	 * from source less than 1 hour ago you get....
	 * 
	 * a million bonus points.  
         *
	 * (Hey, the _very first_ thing the game tells you is 
	 * "Uuuuse the Soooource!!!!"  It's not kidding. :-)
	 *
	 */

A solution to keep this joke *and* allow reproducible builds at the same time 
would be to introduce a --distrobuild build switch which distributions could 
use to disable it.

This could be a Debian specific patch at first, but ideally it should go 
upstream, so that other distros can benefit too.
