Move nano specs hack into our module cmake files. We've been maintaining a downstream patch to disable C++ exception handling, which gives us some headroom before our builds get too big and overwrite themselves at runtime. Forgetting to apply this patch is a constant source of debugging frustration. It turns out it can just be added to our USER_C_MODULES cmake files instead, where it will implicitly be included when building against our modules. 2024-07-03 15:18:44 +00:00			`# Do not include stack unwinding & exception handling for C++ user modules`
