perf test: Skip perf data type profiling tests for s390
Test case 'perf data type profiling tests' fails on s390 with this
error:
# ./perf mem record -- ./perf test -w code_with_type
failed: no PMU supports the memory events
# echo $?
255
#
because s390 does not support memory events at all. According to the
man page, perf annotate --code-with-type only works with memory
instructions only. As command 'perf mem record ...' is not supported
on s390, skip this test for s390.
Output before:
# ./perf test 'perf data type profiling tests'
77: perf data type profiling tests : FAILED!
Output after:
# ./perf test 'perf data type profiling tests'
77: perf data type profiling tests : Skip
Fixes: f60a5c22967b8 ("perf tests: Test annotate with data type profiling and rust")
