Thomas Richter	658a8805cb	perf test: Speed up test case 70 annotate basic tests ... On some s390 linux machine (mostly older models) and with debug packages installed, the test case 'perf annotate basic tests' runs for some longer time. Speed up the test and save the output of command perf annotate in a temporary file. This is used to perform pattern matching via grep command. This saves on invocation of perf annotate which runs for some time.
