So that it can get rid of requirement of a compiler.
$ sudo ./perf test -v 109
109: Test data symbol :
--- start ---
test child forked, pid 844526
Recording workload...
[ perf record: Woken up 2 times to write data ]
[ perf record: Captured and wrote 0.354 MB /tmp/__perf_test.perf.data.GFeZO (4847 samples) ]
Cleaning up files...
test child finished with 0
---- end ----
Test data symbol: Ok
