Builds on emba fail now:

--8<---------------cut here---------------start------------->8---
configure: error: You do not seem to have makeinfo >= 4.13, and your
source tree does not seem to have pre-built manuals in the 'info' directory.
Please install a suitable version of makeinfo.
--8<---------------cut here---------------end--------------->8---

And no, we don't install texinfo every single test run. Performance, and
the like.

I have applied "touch info/emacs" prior the "./configure" step, but then
"make bootstrap" fails with the error shown above.
