Bug#962305: libtommath: Documentation .pdf files embed time

[Vagrant Cascadian]

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

When the build time and timezone vary, the resulting .pdf file includes
an embedded timestamp. It looks like doc/makefile attempts to make the
timestamp reproducible in the generated .pdf, but doesn't catch some
corner cases.

The patch to debian/rules sets FORCE_SOURCE_DATE, which is needed to get
texlive to respect SOURCE_DATE_EPOCH.

The other patch modifies doc/makefile to use SOURCE_DATE_EPOCH directly
rather than a reference timestamp file.

Thanks for maintaining libtommath!

live well,
  vagrant
