I tried and it is working partially.

Calling emacs from /usr/local/sbin works, however when I symlink
/usr/local/sbin/emacs-28.0.50/emacs-28.0.50 to /usr/local/bin I have the
same error:

make[1] : on quitte le répertoire « /home/thierry/tmp/emacs/lib-src »
find native-lisp -type d -exec /bin/mkdir -p "/usr/local/lib/emacs/28.0.50/{}" 
\; ; \
find native-lisp -type f -exec /usr/bin/install -c -m 644 "{}" 
"/usr/local/lib/emacs/28.0.50/{}" \;

So for now what is working best for me is symlinking native-lisp
directory to /usr/local/sbin.
