liboping:

 * avoid polluting config.cache with invalid ncurses related values: liboping itself doesn't depend on ncurses, it however contains a command line application - noping - which requires ncurses and thus tests for it, as freetz doesn't provide noping binary it doesn't specify the ncurses dependency, this results in failing ncurses related tests, which in turn results in wrong values being cached
 * fixes build problems of various ncurses dependent packages
