Hi,

I have a py_binary that depends on a python pip library (grpcio) that has a native extension bundled in. This means that to create a linux container i'd need to have the pip_import rule download the manylinux wheel, not the host one (macos in my case).

Is there a way to force this? Otherwise py_image will happily just bundle up wheels with darwin native libs. py_binary will also only make host-runnable things.
