Do not build Ada code in ncurses
Do not build Ada code in ncurses

When gnat package is installed, the configure script of
ncurses finds it and tries to build some host code. They
are unnecessary for us, and even worse, the compilation
fails (at least for me).

TEST=./make_all.sh ncurses  # with gnat package installed
