When building multiple crates that export Android APIs via flapigen, the final linking step fails with the error: ld error: duplicate symbol: JNI_OnLoad. This only happens on Rust 1.60 and not older versions. This is caused because of rust-lang/rust#83822, which removes support for duplicate symbols on Android targets.

Not sure that going to fix this. This project is designed to work with the idea that only top level crate uses flapigen.
Not the many crate provides C API and somehow combined into big library, the idea that all crates provide Rust API,
and only top level crate provides C API.
