just to point to downstream that firefox78 could have some issues with rustc 1.45.0 : #1640982 - rust 1.45 error: options -C embed-bitcode=no and -C lto are incompatible


This comment intended that lto/embed-bitcode issue to get a compatibility note, but it seems to have been forgotten. Is it too late to add that?
