[PATCH] D55443: [test] Capture stderr from 'tar --version' call as well

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added inline comments.


================
Comment at: test/lit.cfg.py:99
+        stdout=subprocess.PIPE,
+        stderr=subprocess.PIPE,
+        env={'LANG': 'C'})
----------------
If you don't need stderr, remove `stderr=subprocess.PIPE,`

`subprocess.Popen followed by communicate()` can be replaced by `check_output`

`if 'GNU tar' in sout:` does not in Python 3 as `sout` would have type `bytes`, not `str`
