[PING PATCH v2] perf test: Fix test case perf script tests on s390

From: Thomas Richter
Date: Thu Jan 25 2024 - 05:04:19 EST


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 fors s390.

Output before:
# perf test 89
89: perf script tests : FAILED!
#

Output after:
# perf test 89
89: perf script tests : Ok
#

Fixes: 0dd5041c9a0e ("perf addr_location: Add init/exit/copy functions")
