[PATCH] Allow to override build date

[Bernhard M. Wiedemann]

Hi,

I found this patch in the Debian bugtracker 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=826158
and also want it for the openSUSE GNU/Linux distribution
so it might as well go upstream:

Indecription: Reproducible info output
 Honour the SOURCE_DATE_EPOCH environment variable to get a reproducible
 @today value for info output when it is set.
 See https://reproducible-builds.org/specs/source-date-epoch/
