    tools/misc: rework Makefile
    
    Add missing "xen-detect" rule. It only works without it because we
    still have make's built-ins rules and variables, but fix this to not
    have to rely on them.
    
    Rename $(TARGETS_BUILD) to $(TARGETS).
    
    Remove the unused "build" target.
    
    Also, they are no more "build-only" targets, remove the extra code.
