6e14f3baf6 libpfm4: needs NPTL support
Fixes following build failure:
--->---
self_smpl_multi.c: In function 'my_thread':
self_smpl_multi.c:354:2: error: implicit declaration of function 'pthread_barrier_wait' [-Werror=implicit-function-declaration]
  pthread_barrier_wait(&barrier);
  ^
self_smpl_multi.c: In function 'main':
self_smpl_multi.c:450:2: error: implicit declaration of function 'pthread_barrier_init' [-Werror=implicit-function-declaration]
  pthread_barrier_init(&barrier, 0, max_thr+1);
  ^
cc1: all warnings being treated as errors
--->---

And since xtensa, avr32 and bfin don't support NPTL we may remove arch
dependencies as well.

344a1b88ee libpfm4: disable when pthreads barrier support in missing
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
http://autobuild.buildroot.net/results/ea5/ea594807b891cbe1f0eddad7f89d34af160636c4/.

Also, add missing comment arches dependency.

09100a3750 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.
