If rust is currently just hiding these warning when ELF linking then I think it seems reasonable to also just hide them for wasm too.   So the solution here seems like it should be to remove `--fatal-warnings` from the rust toolchain?

Can somebody who uses rust confirm that adding `-Wl,--fatal-warnings` in a normal ELF build will cause it to fail in this way too?  (Is is easy to add link flags in rust to try this out?)
