meta-arm-bsp:linux-linaro-arm: Fix kernel menuconfig task

When calling `bitbake virtual/kernel -c menuconfig` it fails if the
ncurses-dev package is not installed on the host machine.

This patch makes usage of the ncurses library built by yocto if it
is present.

+Subject: menuconfig,mconf-cfg: Allow specification of ncurses location
+
+In some cross build environments such as the Yocto Project build
+environment it provides an ncurses library that is compiled
+differently than the host's version.  This causes display corruption
+problems when the host's curses includes are used instead of the
+includes from the provided compiler are overridden.  There is a second
+case where there is no curses libraries at all on the host system and
+menuconfig will just fail entirely.
+
+The solution is simply to allow an override variable in
+check-lxdialog.sh for environments such as the Yocto Project.  Adding
+a CROSS_CURSES_LIB and CROSS_CURSES_INC solves the issue and allowing
+compiling and linking against the right headers and libraries.
