Hi, I think it would be a good idea to make squeaky's portable pypy builds [1] more official by moving the repo to something like github.com/pypy/portable.

I think it's a good idea for various reasons, in particular:

1. we already link them from pypy.org, although not very prominently

2. they are used as a base for my manylinux-pypy docker image [2], which I'd like to become "the official way to build PyPy wheels" (and thus move it to something like github.com/pypy/manylinux or so).

Does anybody have opinions on this?
