You've stated that your goal is to allow the building of pypy[2|3] with 
pypy[2|3], but that requires several different steps:
1. Make it possible for Python 3 to run the RPython toolchain.
2. Make the RPython toolchain work on 2+3 mixed-mode code bases.
3. Port the interpreter to 2+3-compatible code.

Trying to work on task 3. before resolving its prerequisites is very 
likely to be inefficient and generate unnecessary friction. For now, I 
think you should only work on 1. (which is rather big already). This 
basically means modifying only rpython/.
