[Buildroot] Ncurses wide support

[Ezequiel García]

Currently Buildroot support building the non-wide (non-unicode) ncurses library.

While ncurses support an easy way to enable wide support with a configure option
(--enable-widec), this option builds *only* the wide-enabled library
(aka libncursesw)
and not the vanilla one.

In other words, it's not possible to build both at the same time.

By looking at my Gentoo ebuild -which is also source based- it seems
they solve this by
simply building ncurses twice: first the vanilla, and then (if unicode
is enabled) the
wide-enabled one.

Questions that arise:

1. Does Buildroot support something like this?

2. Should we patch ncurses configure to change this behavior?
(not really a fun solution, given this is an upstream choice)

3. Do we even care?
