ABI tags in 3.8+ dropped the 'm'

[dmulkey-qubitekk]

Hi there,

On line 40 of wheels.py (definition of score_abi under CompatibilityScorer), there's a comment of "Is the m reliable" referring to the 'm' in ABI tags of 'cp36m' or 'cp37m.' In packages with Python 3.8+, the m has been dropped. Examples include matplotlib, scipy, numpy, and Pillow.

The release notes for wheel confirm this. Here's the referenced PR. Looks like it stems from changes described under What's New In Python 3.8.

A (lame?) workaround is to redefine d as follows (haven't checked for passing tests):

d = {'cp%sm' % py_version_nodot: 3,  # Is the m reliable?  
    'cp%s' % py_version_nodot: 3,  
    'abi3': 2, 'none': 1}

Cheers,
-Daniel

Shoot, I checked for preexisting issues, but I didn't notice that someone already submitted a PR addressing this. Sorry! Thanks for making a great package!
