tcl configuration: --with-tcl=prefix is equivalent to passing the --prefix dir to it. If --with-tcl or --enable-tcl are explicitly passed in and tclConfig.sh is not found, fail fatally. When TCL is either explicitly disabled or default search for it fails non-fatally, be more explicit about which components are not available.
