bug#58267: 29.0.50; Native-compiling the same files at every start

[Holger Schurig]

* I compiled Emacs from GIT by myself (version emacs-28.2-159399-g2973f91fb3)
* installed it via GNU Stow into /usr/local/emacs
* whenever I now run "emacs -Q" the same files will always be
byte-compiled according to "*Async-native-compile-log*":

So, when I stop Emacs and start it again, I get the same behavior.

I think the underlying problem is that /usr/local/share is root owned,
and my running Emacs as a user don't have write access. So no *.eln
files end up in this path. And this makes Emacs trying to byte-compile
them again.

Couldn't Emacs byte-compile them at "make" or "make install" steps?
