+From: Jeremy Puhlman <jpuhlman@mvista.com>
+Date: Tue, 25 Feb 2020 22:58:59 +0000
+Subject: [PATCH] gzip with -n for build reproducibilty
+
+The date can get encoded in the header of the gz file, which
+causes the binary files between two different builds of the
+same data to be different. Add -n for reproducibilty
