New issue 2440: extension_suffixes() without cpyext https://bitbucket.org/pypy/pypy/issues/2440/extension_suffixes-without-cpyex... Richard Plangger: The condtion in the file `pypy/module/imp/interp_imp.py:~10` prevents pypy/tools/build_cffi_imports.py to succeed if pypy was compiled without cpyext module.

From my understanding it should be fine to just remove the condition and always include the result of `importing.get_so_extension(space)`.
