Perhaps I had the opportunity to redesign the matter, I would let `-stdlib=libc++` not affect linker options at all. Users just should specify `-lc++` and related options by themselves.

Right, but at least some of these sound like the can or should be solved in libc++ then. Reading https://reviews.llvm.org/D60794, I thought this was not going to happen and the solution should instead be in clang.

What is the ideal solution here? If `-static -stdlib=libc++` is not meant to work, is the working solution documented anywhere that we could link people to? If your blog post isn't official of course :)
