Bug description:
  python-psutil 7.0.0-2 fails to build on ppc64el:

  ```

      )
      def test_against_lscpu(self):
  >       out = sh("lscpu -p")

  psutil/tests/test_linux.py:683: 
  _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 
  psutil/tests/__init__.py:330: in wrapper
      return fun(*args, **kwargs)

  cmd = ['lscpu', '-p']
  kwds = {'creationflags': 0, 'stderr': -1, 'stdout': -1, 'universal_newlines': True}
  flags = 0, p = <Popen: returncode: -6 args: ['lscpu', '-p']>, stdout = ''
  stderr = 'free(): double free detected in tcache 2\n'

      @_reap_children_on_err
      def sh(cmd, **kwds):
          """Run cmd in a subprocess and return its output.
          raises RuntimeError on error.
          """
          # Prevents subprocess to open error dialogs in case of error.
          flags = 0x8000000 if WINDOWS else 0
          kwds.setdefault("stdout", subprocess.PIPE)
          kwds.setdefault("stderr", subprocess.PIPE)
          kwds.setdefault("universal_newlines", True)
          kwds.setdefault("creationflags", flags)
          if isinstance(cmd, str):
              cmd = shlex.split(cmd)
          p = subprocess.Popen(cmd, **kwds)
          _subprocesses_started.add(p)
          stdout, stderr = p.communicate(timeout=GLOBAL_TIMEOUT)
          if p.returncode != 0:

  E           RuntimeError: free(): double free detected in tcache 2

  psutil/tests/__init__.py:497: RuntimeError
  ```

  So `lscpu -p` fails with:

  ```
  free(): double free detected in tcache 2
  ```

  python-psutil 7.0.0-2 builds with util-linux 2.40.2-14ubuntu1 but
  fails with this error with 2.41-4ubuntu2.
