[PATCH] menuconfig: use config scripts to detect ncurses libs

[jlec@gentoo.org]

From: Justin Lecher <jlec@gentoo.org>

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) to assist finding ncurses.

This patch replaces the old heuristic for detection of ncurses libs for
linking the ncurses menuconfig dialog by the use of the config scripts.
This results in the requirement of ncurses version 5.6 or newer for menuconfig.
