    conf: add C++ flags for uninative interoperatility
    
    Create a common include file for compiler flags which allow native binaries to
    be interoperable on a wide range of hosts. In particular the C++ ABI is
    problematic so choose the CXX11 version to allow interoperation between gcc4 and
    gcc5 based hosts. Moving this to a common include instead of uninative.bbclass
    allows uninative to be configured later and used in the eSDK (where its
    mandatory) even if the base configuration doesn't enable uninative by default
    (e.g. nodistro in OE-Core).
