iozone: depends on toolchain with NPTL support

The existent patch is not enough, as pthread_barrier_wait is used, which
isn't implemented in uClibc-ng Linuxthreads.
Remove the patch.

-Dummy pthread_setaffinity_np() when not available
-
-On uClibc configurations that do not use the NPTL thread
-implementation, pthread_setaffinity_np() is not available. This patch
-defines a dummy (empty) implementation of this function for such
-cases.
-
-The only few architectures that do not provide the NPTL thread
-implementation are very likely to be non-SMP architectures, and
-therefore, setting the affinity of the thread is not doing anything
-useful, so having an empty stub for pthread_setaffinity_np() is not a
-problem.
