So that shows this is failing in libtool.  And that's built after
automake, so probably it's only libtool.

It looks like "makeinfo" shouldn't be needed when building a libtool
release, but testing it is.  I think that's because we patch libtool
before building it, and that causes regeneration of a file which
seems to substitute the version into the manual, and then it thinks
it has to rebuild the manual.

We could just tell people to install makeinfo, but that slows down
the first build a bit.  Perhaps the patch can be adjusted to avoid
this.
