Indeed I can reproduce it with:

    make
    touch lisp/international/{ucs-normalize,charprop,uni-special-lowercase}.el
    make

It seems it is newly introduced by the symbol-shorthands
code, which apparently uses just enough more of the `hack-local-variables`
machinery to trigger it.

Not sure what's the best fix for it, but I installed a patch into
`emacs-28` which seems to work around the problem.
Maybe we should drop the lazy loading feature of lisp/international/uni-*
since those files end up preloaded anyway.
