configure.ac: Make sure libcaca can actually be used instead of just checking for...

Original commit message from CVS:
* configure.ac:
Make sure libcaca can actually be used instead of just checking for
/usr/bin/caca-config, so we don't wrongly try to build cacasink when
cross-compiling (fixes #384587).
