Yang Tse 2c61e9c76a Modified configuration script to actually verify if the compiler is good 
enough at detecting compilation errors or at least it has been properly
configured to do so. Configuration heavily depends on this capability, so
if this compiler sanity check fails the configuration process will now fail.
