Yes, and that should probably change (I have an idea for how to do
that).  But the change isn't so trivial, so I think it isn't
appropriate for the branch.  Therefore, I tried to propose a band-aid:
have the readline/readline/doc directory be _always_ on the makeinfo's
include path, so that if someone reconfigures GDB like in the
reproducer, they still get a successful build, albeit with a couple of
sections in the manual they don't need.

Could you please see if my proposal solves the immediate problem?  And
if not, explain what I missed?

That'd contradict GNU conventions: we always include the generated
Info manuals in the release tarballs.

I think this is sufficiently complex to avoid doing that on the
branch.  We could try this on master, of course.  But right now, I'd
like to fix the branch so that we don't have a regression, while still
allowing people to build GDB without having Texinfo installed.

That's true, but I don't see that as a serious enough problem to delay
the release of GDB 11.  Of course, it isn't my call, eventually.
