perf tools: Define _GNU_SOURCE on pthread_attr_setaffinity_np feature check
The man page for pthread_attr_set_affinity_np states that _GNU_SOURCE must be defined before pthread.h is included in order to get the proper function declaration. Define this in the Makefile. Without this defined, the feature check fails on a Fedora system with gcc5 and then the perf build later fails with conflicting prototypes for the function.
