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

to make release 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.

The previous code was added in commit b940783d0a38246fbf7326e9ccf625fd185c062f
by Manuel Moos (@zmanuel)
but only helped when running bootstrap.sh with a .git dir.
However, release tarballs don't have a .git dir.

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