[Distutils] Should abi3 tag be usable on Windows?

[Cosimo Lupo]

I jut found this related pip issue: https://github.com/pypa/pip/issues/4445

(I myself as @anthrotype commented on that thread back in April last year
but then completely forgot...)

After re-reading it now, it's still not clear to me what the resolution on
that issue was.
