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.

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