It turns out that by setting DIST_EXTRA_CONFIG you can tell setuptools to read a supplementary configuration file. This lets us pass options that we normally cannot reach via the bdist_wheel command. Tell the build task to use a build directory outside of the source tree, so that we can clean it before each rebuild. Tell the build_ext task to do parallel builds, as it defaults to not. In my testing this halves the build time of python3-pandas.
