Check for swig version >= 1.3.10 in configure.in, to match the
requirement stated in subversion/bindings/swig/README.
(Is it acceptable to use awk in configure.in? I saw no other uses of it,
but couldn't think of another easy, relatively portable way to extract
swig's version number. And it would have saved me some frustration to
not attempt to use swig with an outdated version.)
