The change required here is smaller than discussed yesterday in the K meeting; the underlying issue was actually just that our build system wasn't adding a compiler flag that's required for
py::module_local()to work properly.Reference from the docs (different error, but contains the instruction to make sure that you're passing this flag): https://pybind11.readthedocs.io/en/stable/faq.html#someclass-declared-with-greater-visibility-than-the-type-of-its-field-someclass-member-wattributes
This PR adds that flag; I have verified that K built using this modified backend fixes my reproduction code from runtimeverification/pyk#551
