I am just seeing the support from config.{guess,sub} and libtool. Nothing in libgcc/config.host, gcc/config.gcc, or libstdc++/configure.host . So you will need to add much more support than just libstdc++ here. Since this was never supported, I am thinking about closing this as invalid but I will let someone else make that call.
