The issue should be now fixed in Emacs master with ead4b914ca.

Have a look at bug#57200.  `update-directory-autoloads' is back again in
97da8eeb7c, but one can also (require 'autoload) by hand.

My suggestion is now apply the following change:

which doesn't emit a warning about obsolete autoload.el.  That should
bring us to the current state of files with Emacs 29.  There is only
difference that the parts

  echo ";; Auto-generated preview-latex.el" > $@

from preview-latex.el rule and

  echo ";; Auto-generated part of tex-site.el" > $@

from auto-loads.el rule don't work.  I couldn't figure out why.  Maybe
others?

Best, Arash
