From e6f976b6d4fdd307b81372e9ffbf94ea93852c90 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 25 May 2016 16:00:00 +0200 Subject: [PATCH] lirc-tools: add patch to fix parallel build issue The lirc-tools package fails to build once in a while in the autobuilders. Some quick analysis of the problematic Makefile.am has revealed one issue. However, since the issue is difficult to reproduce, we could only check that the new solution continue to work, and we're not 100% sure it fixes the entire problem: only the autobuilders can say, over time.
