Well, I didn't want to to tinker with installation files. I hoped that
there was a way to configure it accordingly.

I thought it would be a "more correct" way of installing it. GCC (and
others) install their libraries in prefix/lib and prefix/lib/sparcv9 as
well without needing two separate installations, therefore I was
wondering whether the same can be achieved with Python.

But if this is not possible, then I'll just go for python and python64
as separated installations.
