    ncurses: serialize the tinfo build a little bit
    
    Move ncurses_dll.h to GENHDRS to start with; it's been generated from
    ncurses_dll.h.in for years, so it's not actually in a different category
    than all of the other GENHDRS.  Slap an .ORDER on it to ensure that we
    build ncurses_dll.h and curses.h before any *.c gets compiled.
    
    This should sufficiently address a build race seen downstream where
    ncurses_dll.h is present but not yet populated.
