Allow Clang to compile without libc++
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).
