Bug#974957: dynare: reproducible builds: PDFs contain date of build

[Vagrant Cascadian]

Source: dynare
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

Several PDFs shipped in dynare packages embed the build date:

  https://tests.reproducible-builds.org/debian/rb-pkg/bullseye/amd64/diffoscope-results/dynare.html

  ./usr/share/doc/dynare/gsa.pdf.gz
  7 	October·29,·2020	7 	December·2,·2021


The attached patch fixes this by setting FORCE_SOURCE_DATE=1 in
debian/rules, which texlive needs in order to respect SOURCE_DATE_EPOCH,
which is set during debian package builds to the timestamp in the latest
debian/changelog entry.

live well,
