perf tools: Provide stub for missing pthread_attr_setaffinity_np
uClibc Linuxthreads.old doesn't support the pthread_attr_setaffinity_np()
functioo:
----------------->8-----------------------
CC bench/futex-hash.o
CC bench/futex-wake.o
bench/futex-hash.c: In function 'bench_futex_hash':
bench/futex-hash.c:161:3: error: implicit declaration of function
'pthread_attr_setaffinity_np' [-Werror=implicit-function-declaration]
ret = pthread_attr_setaffinity_np(&thread_attr, sizeof(cpu_set_t),
&cpu);
^
bench/futex-hash.c:161:3: error: nested extern declaration of
'pthread_attr_setaffinity_np' [-Werror=nested-externs]
----------------->8-----------------------
So introduce a test to check that and if not available provide a stub.
