This is usually done by requiring an exported symbol saying that the code is GPL compatible. GCC does it this way: https://gcc.gnu.org/onlinedocs/gccint/Plugin-API.html

But you cannot call that a FFI then. A FFI is the abbrevation for "Foreign Function Interface", not "Friendly Function Interface". FFI's are not sugar coated.
