ncurses: speed up host build by disabling static library building

For the host variant of packages, we normally only build the shared
libraries. However, ncurses uses non-standard options to select
between shared/static and therefore the host variant was building both
of them, even though the static libraries were unused.

By passing --without-normal, we disable the build of static
libraries. It saves a bit of disk space, and on my laptop,
host-ncurses takes 26 seconds to build instead of 40 seconds.
