Rolf Eike Beer 854e76237c FindRuby: clean up querying variables from Ruby ...

Newer Ruby versions (from 1.9 onward) seem to warn if you query Config::CONFIG
and print a warning to use RbConfig instead. RbConfig seems to also work in
older versions, at least in 1.8. Use a macro to query RbConfig first and only
if that doesn't give anything fall back to Config.
