crossgcc: Fix compilation on Clang systems

Most cross compilers fail to compile on systems with Clang being the
    default compiler (OS X and some BSDs). Clang dislikes some of GCC's
    autogenerated code. We also missed switching CFLAGS to CXXFLAGS when GCC
    switched to C++ compilation per default.
