    cross: export CC family from BUILD_* for cross compilers
    
    cross-compilers are native recipes that need to be compiled by the host's
    compiler. However they do not use native.bbclass
    
    As a consequence, the various CC, CXX etc environment variables are not
    correctly set and they will not honor the host compiler name provided
    by the BUILD_* variables.
