Something was off, as that patch said the timestamps of 
build-aux/config.guess and build-aux/config.sub were both 2022-09-17, 
whereas the master branch said they were 2023-07-20 and 2023-07-31 
respectively. I suppose this patch was generated against some other 
Emacs branch?

Anyway, these two files (along with other Gnulib-derived files in the 
Emacs repository) are updated automatically by admin/merge-gnulib. Today 
I did such an update on the master branch, so config.guess and 
config.sub are now updated to their latest versions.

I then reproduced the problem that Gerd mentioned. Gnulib's config.guess 
etc. tend to be more up-to-date, and anyway the Emacs build is more 
reproducible if we use the Emacs repository version of config.guess etc. 
(instead of whatever version the developer's Autoconf happens to have), 
so I installed the attached patch which fixed the problem for me.

Boldly closing the bug report; we can reopen it if there are still 
issues here.
