[PATCH 2/2] kconfig: use config scripts to detect ncurses libs

[jlec]

From: Justin Lecher <jlec@xxxxxxxxxx>

When building ncurses with --with-termlib several symbols get moved from
libncurses.so to libtinfo.so. Thus when linking with libncurses.so, one
additionally needs to link with libtinfo.so. Ncurses provides a config script
(ncurses5-config) or in very recent version even a pkg-config module to assist
finding ncurses.

This patch makes use of it to detect the necessary libs for linking of the
ncurses nconfig dialog
