That's indeed what we in Emacs-29.

Loading `site-load.el` in the first dump is a bad idea because files
haven't been compiled yet.

Loading `site-load.el` in the second dump is a bad idea because:
- as currently written, the site-loaded files aren't compiled, so it's
  too early to dump them.
- if you change the build to byte-compile them before the second dump,
  you'll be byte-compiling them with the bootstrap-emacs which might
  work but will lead to a slower compilation.

So, I suggest something like:

    mv lisp/site-load.el lisp/my-site-load.el
    make
    rm src/emacs
    mv lisp/my-site-load.el  lisp/site-load.el
    mv lisp/my-site-load.elc lisp/site-load.elc
    make

So the first 2 dumps are "normal" without any site-loaded files, and
that's followed by a 3rd dump, where all the ELisp files are already
byte-compiled.
