[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=344a1b88ee46a5b26613d4177979039379373b73
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The old linuxthreads pthreads implementation does not support barriers.
Disable libpfm4 for arches that don't have either NPTL or new linuxthreads
pthreads implementation.

Fixes
