libpfm4: needs NPTL support
Fixes following build failure: --->--- self_smpl_multi.c: In function 'my_thread': self_smpl_multi.c:354:2: error: implicit declaration of function 'pthread_barrier_wait' [-Werror=implicit-function-declaration] pthread_barrier_wait(&barrier); ^ self_smpl_multi.c: In function 'main': self_smpl_multi.c:450:2: error: implicit declaration of function 'pthread_barrier_init' [-Werror=implicit-function-declaration] pthread_barrier_init(&barrier, 0, max_thr+1); ^ cc1: all warnings being treated as errors --->--- And since xtensa, avr32 and bfin don't support NPTL we may remove arch dependencies as well.
