+Subject: [PATCH] menuconfig,check-lxdiaglog.sh: Allow specification of ncurses location
+
+Upstream-status: Submitted
+
+[ based on: https://lkml.org/lkml/2013/3/3/103 ]
+
+This patch syncs up with the way the menuconfig ncurses / curses
+is detected and the HOST_EXTRACFLAGS works in the Linux kernel
+and it allows the menuconfig to work with a sysroot version
+of the curses libraries.
+
+---
+
+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.
