Invalid python_requires in setup.py - ">=3.4.*" not allowed

[ColinKennedy]

Reference issue:
AcademySoftwareFoundation/rez#876

Steps to reproduce

• Install astroid

python3.6 -m pip install astroid==2.2.0 --user

• Run this

import os
from distlib import database


def main():
    """Run the main execution of the current script."""
    path = os.path.join(os.path.expanduser("~"), ".local", "lib", "python3.6", "site-packages")
    distribution = database.DistributionPath([path])
    distributions = list(distribution.get_distributions())


if __name__ == "__main__":
    main()

Current behavior

• Raises this exception - ValueError: '.*' not allowed for u'>=' constraints

Expected behavior

distributions should be a non-empty list, containing at least astroid 2.2.0 as one of its entries

python -c "from astroid import __pkginfo__; print(__pkginfo__.version)" output

$ python3 -c "from astroid import __pkginfo__; print(__pkginfo__.version)"
2.3.3
