+From: Jean Delvare <jdelvare@suse.de>
+Subject: Use -DALIGNMENT_WORKAROUND on arm as well
+
+The arm build log shows a lot warnings about casts increasing the
+required alignment of target type. This suggests that this
+architecture needs to use the slower byte access which is enabled by
+-DALIGNMENT_WORKAROUND.
