  ```
   19: 'import perf' in python                                         :
  --- start ---
  test child forked, pid 2640936
  python usage test: "echo "import sys ; sys.path.insert(0, 'python'); import perf" | '/usr/bin/python3' "
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  ImportError: tools/perf/python/perf.cpython-311-x86_64-linux-gnu.so: undefined symbol: perf_pmus__supports_extended_type
