build: use cmake to pass -std=c++11
Rather than manually checking for support for the spelling of the C++
standard, indicate to CMake that we require that the compiler support
C++11 and that we compile without the GNU extensions. This simplifies
the flags handling in libc++abi itself by relying on CMake to translate
the flag and add it as appropriate.
