Subject: [PATCH] menuconfig,check-lxdiaglog.sh: 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.
