?

If all the info file are already there, make will see that they are newer
than their dependencies, so it won't try to rebuild them.
There's no need to "touch" anything, and I would/did not recommend
doing so.

--without-makeinfo was always irrelevant in _releases_, where the info
files are pre-built.

They can always do "make lisp" (I think) instead of "make [all]".

Or you can add a target "all-noinfo" which is just "all" without "info",
but I don't know who the users of such a target would be.
