From 7098e955d8d0a061132aaec1429fc032e3d2edab Mon Sep 17 00:00:00 2001
From: Andrew Robbins <contact@andrewrobbins.info>
Date: Mon, 10 Dec 2018 20:31:42 -0500
Subject: [PATCH] Require a recent fontforge for reproducibility
The required version is set to 20171220 which is the earliest
date from which fontforge built from source was able to produce
fonts deterministically. "20171220" refers to upstream revision
69e561773b91e37096a855f0353b1d6781a61250
Note there was not an actual dejavu-fonts release made on 2017-12-20;
the date is intended to be both a reference point, as previously
described, and a mechanism to prevent non-deterministic fonts being
produced by Libreboot's build system due to an unsupported version
of fontforge being used.
