Sigh... no, while that would no doubt fix a few tests, what users were
asking for (and what we now build by default) is a single binary for
gcc/*nix systems that can be used irrespective of whether they're using
threads or not. In other words we want to fix the Boost ABI to be the same
as the libstdc++ ABI, no matter whether a default threading-single build is
done or not.

Hope this is making some sense, but I don't know what the correct solution
