Passes for me too when I run in tools/perf/ dir:

[root@...vtune39 acme]# pwd && tools/perf/perf test 16 48
/root/abudanko/kernel/acme
16: Setup struct perf_event_attr                          : Skip
48: Synthesize attr update                                : Ok
[root@...vtune39 acme]# cd tools/perf/
[root@...vtune39 perf]# pwd && tools/perf/perf test 16 48
[root@...vtune39 perf]# pwd && perf test 16 48
/root/abudanko/kernel/acme/tools/perf
16: Setup struct perf_event_attr               : Ok
48: Synthesize attr update                     : Ok
