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.
