Ah. With geos-2.2.3, the configure checks pass, but the build fails.

The GEOS configure checks should actually do some checking. Apart from
the version issue, there's no LOC_CHECK_LIBS or similar, so the checks
will pass even if the library is entirely absent.

LOC_CHECK_LIBS checks for a specific symbol, so it should be
straightforward to check for a symbol which is only present in 3.x.
