[pypy-dev] I reinstated the nightly run of cpython tests against pypy-c

[Samuele Pedroni]

I switched to only test these combinations:

1) hybrid gc thread old-style allworkingmodules

the result of a try run for this one can be seen at the usual place:

http://www2.openend.se/~pedronis/pypy-c-test/allworkingmodules/56156/index.html

although just the % doesn't tell much it seems we had some regressions 
in some fundamental tests,
like test_builtin

also our modified test_descr segfaults with this combination/these days 
it seems

2) stackless old-style allworkingmodules
