bug#33977: /configure.ac: search for puts() in libtinfow

[Дилян Палаузов]

Hello,

on my system I have only the wide variant of ncurses, so I have libncursesw, 
libtinfow, libformw withot libncurses or
libtinfo.  puts() is in libtinfow. ./confugure fails, as it cannжв find puts() 
in the libraries it searches.  Fix
follows.

Regards
  Дилян
