__u64 maybe an unsigned long, it may also differ from the format expected by PRIu64. Add a cast to silence the warning:
tools/lib/perf/tests/test-evsel.c:176:33: error: format specifies type 'unsigned long long' but the argument has type 'unsigned long' [-Werror,-Wformat] __T_VERBOSE("count = %llu\n", end - start); ~~~~ ^~~~~~~~~~~ %lu
