* mpich: add 3.4.3, 4.0, 4.0.1 * mpich: add url_for_version function For versions 4.0 and up, get tarballs from GitHub. This will help with CI builds, since the MPICH website denies the urllib user-agent from downloading release tarballs. * mpich: disable cuda support MPICH is failing to build in CI due to a configuration script bug in detecting CUDA support. Disable CUDA support by default until we add a proper variant.
