[PATCH 1/2] menuconfig: optionally use pkg-config 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.

The ncurses pkg-config module will be used to detect the necessary libs for
linking. If not available the old heuristic for detection of the ncurses libs
will be used.
