[PATCH 1/2] Use config scripts to detect ncurses libs for menuconfig

[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 makes use of it to detect the necessary libs for linking of the
ncurses menuconfig dialog.
