The Intel compiler does support C++11 options on the command-line.
configure.exe will correctly try to run it, but the test would fail for
incorrect reasons.
First, we need to pass the option -Qstd=c++11 to enable it.
Second, on Windows, the GCC experimental define isn't defined, nor is
__cplusplus updated yet. So we have to rely on the Intel-specific macro.
Third, we need CONFIG += console so that the application succeeds in
linking against a main() function, as opposed to a WinMain one.

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.
