There's a failure here on Alpine Linux:
"error: implicit declaration of function 'pthread_attr_setaffinity_np';
did you mean 'pthread_setaffinity_np'? [-Werror=implicit-function-declaration]"

It looks like "pthread_attr_setaffinity_np" is not available on Alpine Linux. However,
other affinity functions such as "pthread_setaffinity_np" are present. Is there a guard that
I can use here to check if the pthread_*_np functions are available, similar to RTE_HAS_CPUSET for cpuset?
