    travis: use matching C++ for GCC version
    
    When we use GCC 5.x, we need to install the C++ compiler and the C
    compiler together because QEMU tests for feature flags against the C
    compiler and assumes the C++ compiler has them. We also have to
    ensure that GCC C++ is used. Have to do the modification of the CXX variable
    in two steps to ensure we support older versions of bash in use by the
    test machines. While we're at it simply how we select our compiler.
