checkInputs used to be added to nativeBuildInputs. Now we have
nativeCheckInputs to do that instead. Doing this treewide change allows
to keep hashes identical to before the introduction of
nativeCheckInputs.
Was broken after python3.8 upgraded to 3.8.6 due to this change:
bpo-41314: Changed the release when from future import annotations becomes the default from 4.0 to 3.10 (following a change in PEP 563).
The build is currently broken on master and 20.03. This upgrades to the latest
version and also disables the bad py2 test. I spent a long time trying to figure
out what the issue is, but since it's disabled upstream on python3 anyways let's
just skip it on python2 as well.
