From 6102726147a6e81fd7ec209db14337055a99b84b Mon Sep 17 00:00:00 2001
From: Alexey Neyman <stilor@att.net>
Date: Sat, 7 Nov 2015 23:31:46 -0800
Subject: Change ncurses to a companion library.

Currently, builds for build and target (matching the current
implementation). Need to add building for host for canadian crosses.

TIC_PATH is removed - configure in ncurses searches $PATH, so it finds
'tic' in buildtools anyway. Arguably unneeded code for MacOS also
removed, with a FIXME comment for validation by someone using MacOS.
