[New-bugs-announce] [issue19333] distutils.util.grok_environment_error loses the error message

New submission from Marius Gedminas:

Steps to reproduce:

$ python -c 'from distutils.util import grok_environment_error as e; print(e(IOError("message")))'

What I expect to see:
error: message

What I get instead:
error: None

This is a problem because it hides the error message in a real-life use case: trying to use the latest setuptools in an ancient virtualenv (see [1]).  TL;DR version:
- sysconfig (in the standard library) raises IOError(msg),
- which is then caught and passed throughdistutils.util.grok_environment_error(),
- which then returns an unfriendly 'error: None'.
