    gccrs: Use late name resolution on extern crates
    
    Late name resolution was initially not run on extern crate since the
    content within the functions was not used. But function return type is
    resolved within the late name resolver hence why we cannot skip it.
    
    gcc/rust/ChangeLog:
    
            * rust-session-manager.cc (Session::load_extern_crate): Run late name
            resolver on extern crates.
