I think you are trying to do something that isn't supported.  Andrea,
am I right?

Your original idea was to add stuff to loadup, not to dump an already
dumped Emacs, and with AOT *.eln stuff on top of that.  Preloaded
*.eln files are handled specially by loadup.el during the dumping
process, and you tried doing that without observing the protocol of
*.eln dumping.
