From 9dd7a8b9376b4fb6b82422899e0ed7b8606c73ce Mon Sep 17 00:00:00 2001
From: Andrew Robbins <contact@andrewrobbins.info>
Date: Thu, 27 Dec 2018 23:37:07 -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
the non-LGC subset of DejaVu 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.
