Bug#825504: clang-3.6: clang++-3.6 does not find libstdc++ headers on !linux

[Andreas Beckmann]

Package: clang-3.6
Version: 1:3.6.2-3
Severity: important

Hi,

clang++-3.6 does not work properly on kfreebsd-amd64, and I'd expect the
same happens on the other non-linux architectures, too:

$ echo '#include <iostream>' | clang++-3.6 -v -x c++ -E - >/dev/null
