Clang is perfectly able to deal with the libstdc++ headers. The
problem on Mac is that those headers are mightily old (from GCC 4.2),
so they are insufficient for C++11 support.
So make a more accurate test. This allows Clang to enable C++11 in the
presence of newer libstdc++ header (e.g., Clang on Linux or Clang on
FreeBSD).

Also check for c++11 support in configure.exe (which is also used by MinGW builds).
The c++11 check is therefore moved from 'unix' to 'common' directory.
