    distutils-common-base.bbclass: Define commonly used compiler variables
    
    This is inspired from
    https://github.com/python/cpython/blob/master/configure.ac
    
    Helps cross compiling python C modules in some cases where they do
    not respect normal CFLAGS
    
    Errors like using gcc to link when compiler is clang is fixed
