After a brief discussion on #postgis we decided to
drop the GEOS_CAPI_VERSION part. We want to expose
a single version, which is *release* version, not
any *abi* version.

I'm still unsure about these two alternatives for
the geos-config part:

(1)

(2)

Maybe, we don't need any of the two, as long as the --ldflags
switch doesn't output either -lgeos or -lgeos_c
(the geos.m4 macro can do this for foreign packages)
