+Subject: [PATCH] copy-firmware: Do not fail without GNU parallel
+
+Some distributions (including Red Hat Enterprise Linux and its siblings)
+do not ship the GNU `parallel` command or include them in their build
+environment. They do, however, include automatic build flags that try to
+pass -jN to make.
+
+Instead of treating this as a failure, just warn the user that parallel
+builds are not supported without the GNU `parallel` command and just
+continue with serialized execution instead.
