For Python, we:

 1/ Need a host-python whose version matches the one of the target
    python being built.

 2/ Need some special host tools that are built as part of the
    host-python build, in order to build some stuff for the target
    python.

So unfortunately, it's not straightforward to use the Python of your
distribution.

Best regards,

Thomas
