perf test: Add a test case for SDT event
Add a basic test case for SDT event support. This test scans an SDT
event in perftools and check whether the SDT event is correctly stored
into the buildid cache.
Here is an example:
----
$ perf test sdt -v
47: Test SDT event probing :
--- start ---
test child forked, pid 20732
Found 72 SDTs in /home/mhiramat/ksrc/linux/tools/perf/perf
Writing cache: %sdt_perf:test_target=test_target
Cache committed: 0
symbol:test_target file:(null) line:0 offset:0 return:0 lazy:(null)
test child finished with 0
---- end ----
Test SDT event probing: Ok
