The terminfo library is commited to netbsd trunk on 2010 feb. 03 and
that is between netbsd 5.99.24 (2010 jan 19) and 5.99.25 (2010 mar
29).  The version symbol __NetBSD_Version__ is defined in sys/param.h
like this:

#define __NetBSD_Version__      599002600       /* NetBSD 5.99.26 */

but the header file isn't handy as FreeBSD's osreldate.h (it includes
some other header files and not suitable to create Makefile.)

Instead, I've found that we can use HAVE_TERM_H.  /usr/include/term.h
is is header file for terminfo.

I built emacs-23.2 on following two systems with applied patch below.
The former has terminfo but the latter doesn't.
