rust-cpython: fix build for MacOSX

MacOSX needs special link flags. Quoting the README of rust-cpython:

  create a `.cargo/config` with the following content:

  ```
  [target.x86_64-apple-darwin]
  rustflags = [
    "-C", "link-arg=-undefined",
    "-C", "link-arg=dynamic_lookup",
  ]
  ```

This is tested with Python 2.7 (Anaconda install) and Python 3
(Homebrew install)

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
