I am not able to test this (since all my systems have a libtinfo.so, 
which gets picked up), but I think it makes sense.  If you have a system 
where the only ncurses available is configured with:

   --with-termlib --with-shared --enable-widec

you end up with libtinfow.so and no libtinfo.so.  Any objections?  I can 
take care of ChangeLog and commit message since it is a very small 
change, but next time please make sure to follow the checklist [1].

Thanks,

Simon
