I think the issue is slightly more complex.

Andrea, is native-compilation supported with unexec, or only with
pdumper?  If the former, where in the code and when do we load the
preloaded *.eln files? are they dumped into the Emacs executable?

If we don't support native-compilation with unexec, we should reject
that combination in configure, right?
