Subject: [PATCH 1/4] set SOURCE_DATE_EPOCH from changelog
if requested by macro
to allow for more reproducible builds of packages.
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.
(cherry picked from commit 0e87aed1785d0531c40b23889f8338744f6abb3a)
