 libcurses.so lists libterminfo.so as NEEDED.  I vaguely recall that
 the new binutils are more strict about exposing such symbols to the
 main program (that explicitly lists only -lcurses, but also refers a
 symbol that curses brings in via its NEEDED list).
 
 The dynamic linker knowledge is completely swapped out of my head, but
 we need to arrange for -lcurses to make terminfo symbols available b/c
 that's how x/open specifies it.
