[PATCH 1/2] 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) or in very recent version even a pkg-config module to assist
finding ncurses.

The old heuristic for detection of ncurses libs will be extended to the
pkg-config and the config scripts.
