From 199cef0e8a50b20d0ee6fefd1d4cf3372eba7728 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Fri, 19 Aug 2016 16:28:17 +0100 Subject: busybox: Add parallel make fix We're seeing regular parallel make failures in applet headers in busybox. This adds a patch to try and avoid the issue, building upon a fix already backported from upstream. The patch has been sent to upstream.
