All the files get a proper resource when built for Wine. It's only an issue when cross-compiling to a Windows binary, since the PE compiler doesn't do the same magic.
So, the dlls would be affected too, when cross-compiled? Or am I misunderstanding something here? Well, we don't really need to have it work when cross-compiled, I just thought it would be nice to have.
