Run linux kernel make menuconfig on osx yosemite

linux-kernel-make-menuconfig-yosemite.md

install ncurses, via $ brew install ncurses

edit the scripts/kconfig/Makefile, put HOSTLOADLIBES_mconf += -L/usr/local/opt/ncurses/lib -ltinfo, where the libtinfo.dylib is just a symlink to libncurses.dylib

hit the scripts/kconfig/lxdialog/check-lxdialog.sh, this is ugly!

				exit
