le fails to cross build from source, because it uses AC_RUN_IFELSE to
figure out what ncurses' bool type actually is. Fortunately, all that we
know can be determined using compile test bisection
(AC_RUN_IFELSE/AC_CHECK_SIZEOF). Please consider applying the attached
patch to make le cross buildable.
