[Python-modules-team] Bug#884667: 2to3 binary moved to it's own 2to3 package

[Matthias Klose]

Package: src:pycxx
Severity: serious
Tags: sid buster

The 2to3 binary is now built using Python3, and therefore had to move out of the
python (2) package. It's now provided in it's own 2to3 package.  Please add a
build dependency on 2to3, and check if the autopkg test dependencies need an
update as well.
