Subject: [PATCH 2/2] Allow to override build date with SOURCE_DATE_EPOCH

to make builds reproducible.
See https://reproducible-builds.org/ for why this is good
and https://reproducible-builds.org/specs/source-date-epoch/
for the definition of this variable.

This date call works with different variants of date (GNU, FreeBSD, ...).

This patch was done while working on reproducible builds for openSUSE.
