I don't understand yet the packaging requirements, is it not possible to
copy additionally the native-lisp/ folder to the package?

So far I could compile (locally) the current pretest 28.0.91 version
--with-native-compilation.

Then I tried to build (with build.zips.sh) a snapshot of the
masterbranch --with-native-compilation on the same system.  And now
./configure is complaining:

  configure: error: Elisp native compiler was requested, but libgccjit was not 
found.

Does Emacs-29 has different requirements?
