So basically no one builds Org, including the manual, on their own
system?  Even not the Org developers?

This is not needed for the emacs-28 branch, so I meant master.

Your Emacs is probably built with optimizations, whereas mine isn't.
The optimized version build org.info in about 30 sec, as I said, which
is not very different from your timing.
