I fully back this resolution. It is very often that a build server
(whether it is for us to do autobuilds, or a production build server)
lacks such libraries.

So, we have to fix such build failures by either:
  - adding a dependency on host-ncurses, or
  - disabling ncurses/termcap support for the host tools if it makes
    sense and it is possible, otherwise revert to depending on
    host-ncurses.

Thank you!

Yann E. MORIN.
