Yes, just at configure time:

    ./configure --target-list=x86_64-softmmu --python=/usr/bin/python3

I'm building and running tests in-tree, if that makes a difference.

But maybe it's actually not so bad if at least one of us still tests
with Python 2 as long as we haven't officially removed support for
that...
