The user stack dump feature was recently added for powerpc. But there
was no test case available to test it.
This test works same as on other architectures by preparing a stack
frame on the perf test thread and comparing each frame by unwinding it.
$ ./perf test 50
50: Test dwarf unwind : Ok
User stack dump for powerpc: https://lkml.org/lkml/2016/4/28/482
