bug#48578: 28.0.50; Native-compiled files of some preloaded files not loaded at dump time

[Eli Zaretskii]

Something strange is going on on this GNU/Linux system, unlike other
systems where I build Emacs with native-compilation: when dumping,
some of the preloaded files seem to be loaded in their byte-compiled
form, not native-compiled form.  The files are the ones loaded at the
very beginning of 'loadup':

  Loading emacs-lisp/byte-run...
  Loading emacs-lisp/backquote...
  Loading subr...
  Loading version...
  Loading widget...
  Loading custom...
  Loading emacs-lisp/map-ynp...
  Loading international/mule...
  Loading international/mule-conf...
  Loading env...
  Loading format...
  Loading bindings...
  Loading window...
  Loading files...

All the preloaded files after these ones are loaded as native-compiled
Lisp, as expected.

I forced native compilation of the offending files, and verified the
corresponding *.eln files are refreshed in the native-lisp directory,
but the problem persists.

Why does this happen, and how do I fix it?
