--with-python=/path/to/python.binary is enough. We have the same in
Samba where a secondary build against another python interpreter is
regulated with '--extra-python' pointing to the Python's executable.

I don't think we need --with-default-python=2|3 at all. Once you have a
Python binary, you can discover the flavor in the code:
$ python -c 'import sys; print sys.version_info.major'
2
