I agree with Paul here.  I think checking Python version is sufficient.

This

  https://docs.python.org/3/c-api/object.html#PyObject_Hash

and a quick web search for Py_hash_t seems to indicate that we should
check for Python >=3.2, not just 3.

I'd be fine with providing a fallback Py_hash_t in python/python-internal.h,
where we already do a series of fallback definitions and fixes for older
Python, such as e.g. Py_ssize_t.
