emacs-24 broken logic for terminfo on netbsd

[Glenn Morris <rgm@gnu.org>]

It seems to me that emacs-24's configure.in has broken logic for using
terminfo on netbsd, and so will have been using termcap instead.

configure.in refers to $ac_cv_search_tputs, which is no longer set
anywhere in configure since the removal of

  AC_SEARCH_LIBS(tputs, [ncurses terminfo termcap])

(see eg emacs-23 branch)

It seems to me that the following patch in emacs-24 would restore the
emacs-23 logic.

Has anyone been building the pretests on netbsd and can confirm?
