From 09100a37507d2534503c0a1ac3857fc4571304e5 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 3 Dec 2013 20:27:18 +0100 Subject: [PATCH] libpfm4: needs thread support Fixes: http://autobuild.buildroot.net/results/73d736dd3c8a70358ef4b19a63dda46178cf8bf1/ Note that the propagation of the thread dependency to the oprofile package is a little bit non standard, because oprofile selects libpfm4 only on the PowerPC architecture. So we ensure the thread dependency is only enforced on PowerPC, and a separate comment is displayed when thread support is not available, but the PowerPC architecture is used.
