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.
