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.
