    Cpp: Set -std=c++11 also if CXXCPP is already set
    
    * m4/ax_cxx_compile_stdxx.m4 (AX_CXX_COMPILE_STDCXX): Set CXXCPP if
    neccessary.

    This fixes the build with scan-build where CXXCPP is already set but
    does not include stdc++11. While this deviates from the
    autotools-archive version of the script it does not make sense
    to me first to check if stdc++11 needs to be set and then not
    set it.
