I.e. -static-libstdc++ only works on Darwin with a patch which I got fed up with pinging after 4 or so times. NOTE: AFAIR clang doesn't support that option anyway, so it would not be available at stage 1 where clang is the bootstrap compiler. However, the existing compiler build process points explicitly to the just-built libstdc++ convenience lib IIRC (the built tools are statically linked with the lib). So that info ought to be available to the Ada build (I'm pretty sure all the -B etc. is passed through).
