Allow to override build date with SOURCE_DATE_EPOCH
in order 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. Note: This date call is designed to work with different flavors of date (GNU, BSD and others).
