+From f982a712979619dbae2c6e0d741757e2ce94be11 Mon Sep 17 00:00:00 2001
+From: Bruce Rogers <brogers@suse.com>
+Date: Wed, 6 May 2020 15:03:02 -0600
+Subject: [PATCH] [build] Be explicit about -fcommon compiler directive
+
+gcc10 switched default behavior from -fcommon to -fno-common. Since
+"__shared" relies on the legacy behavior, explicitly specify it.
