    xen/compiler: address violation of MISRA C Rule 20.9
    
    The rule states:
    "All identifiers used in the controlling expression of #if or #elif
    preprocessing directives shall be #define'd before evaluation".
    In this case, using defined(identifier) is a MISRA-compliant
    way to achieve the same effect.
