in my experience clang++ does not play well with libstdc++ in c++11 mode
... at least std::thread is completely broken ... this is a known issue
and the bug report already half a year old ... without any activity ...
but i suppose the reason is simply that for the clang sponsors
libstdc++/c++11 compatibility is not relevant ...
