If the package is creating at least one pure Python wheel, check whether
the baseline package contents (i.e. everything but compiled Python
modules, extensions and .dist-info) match between implementations.
This is meant to ensure that we can safely optimize builds by reusing
pure Python wheels from previous builds.
