In linux next repo, test case 'perf script tests' fails on s390.
The root case is a command line invocation of 'perf record' with
call-graph information. On s390 only DWARF formatted call-graphs are
supported and only on software events.
Change the command line parameters for s390.
Output before:
# perf test 89
89: perf script tests : FAILED!
#
Output after:
# perf test 89
89: perf script tests : Ok
#
Fixes: 0dd5041c9a0eaf8c ("perf addr_location: Add init/exit/copy functions")
