+    xen/kconfig,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.
