    tools/include/xen-foreign: avoid to rely on default .SUFFIXES
    
    When a rule isn't a pattern rule, and thus don't have a %, the
    value of the automatic variable stem $* depends on .SUFFIXES. GNU make
    manual explain that it is better to avoid this "bizarre" behavior
    which exist for compatibility.
    
    Use $(basename ) instead. So we can one day avoid make's build-in
    rules and variables.
