Current perf test code tries to execute python version 2 in order to test attributes on perf_event_open syscall. However it's not default python version anymore a system can have python v3 only or v2 with a different name (e.g. python2). So if there's no such python interpreter with the name 'python', the test would fail like this (yes, it's happened on my new archlinux laptop :). 13: struct perf_event_attr setup :sh: python: command not found FAILED! As we can pass name of the python interpreter on make, use it for the attr test also.
