Hi Mathieu, Applying both your patch and my patch works for me, in both pure and non-pure environments. I would suggest taht we also hide clang in the same way as gcc is hidden (in favour of clang-toolchain) to avoid confusion, but otherwise it seems these two patches together at least get things to a working state!
I'd like to see make-clang-toolchain allow you to pick between a specific libstdc++ or libc++, but that requires more thinking so I think ideally it'd be better to apply these patches first to get things to a fixed state.
