[pypy-dev] Refcount garbage collector build error

[Maciej Fijalkowski]

Hi Florin

The refcount garbage collector is only marginally supported (as far as
our tests go), it's definitely neither tested nor really supported
when translated, it was always very slow for example. (and as you
noticed, there is no support for weakrefs for example)
