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.
