[21.5] Check for ar, fix 2.13-ism

21.5 Not relevant to 21.4. Sun hides utilities such as ar; this patch makes configure barf, rather than letting you get all the way to installation. The second hunk in configure.ac is a literal translation of the Autoconf 2.13 macro to 2.5x. I wonder if maybe `long' wouldn't be a better choice? Is it worth doing up config.h.in?
