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

[root@nntvtune39 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@nntvtune39 acme]# cd tools/perf/
[root@nntvtune39 perf]# pwd && tools/perf/perf test 16 48
[root@nntvtune39 perf]# pwd && perf test 16 48
/root/abudanko/kernel/acme/tools/perf
16: Setup struct perf_event_attr : Ok
48: Synthesize attr update : Ok
