In order to be able to run the bash/subcommand-based testsuite directly
from perf test a new perf-test entry has been created for it.
The driver (suite.c) runs all the tests that it finds in the testsuite
directory: tools/perf/testsuite/ (rather ./testsuite as it expects it
it being run from the perf's directory).
In case the testsuite is not found, the testcase is skipped. If this is
not the desired behaviour, some packaging will be needed.
Usage:
./perf test suite
or
./perf test suite -v
(for the verbose output)
