On most linux systems echo supports c-syle escapes with "-e". I'm
guessing which ever echo you're getting dosesn't do that.

I think the best fix is to ensure you're getting bash as your shell.

A nasty hack would be to make check-lxdialog.sh do something like:
(echo ' #include CURSES_LOC';echo 'main() {}') | gcc '-DCURSES_LOC=<ncurses.h>' -DLOCALE -DKBUILD_NO_NLS -lncurses -xc - -o .lxdialog.tmp

But you'll likley find other palces it breaks.
