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.
