    xen/test/livepatch: Regularise Makefiles
    
    In xen/test/livepatch/Makefile:
    
      Provide a `build' target, as most of the
      subdir-invoking Makefiles elsewhere expect.
    
    In xen/test/Makefile:
    
      Replace the two open-coded targets with a generalised pattern rule
      which descends into each of SUBDIRS.  This allows `install' to work
      too (it is already supported by xen/test/livepatch/Makefile).
    
      Provide an explicit default target of `tests', and an `all' target
      (which is conventional).
    
      Suppress entry into the xen/test/livepatch subdir when we are
      building for i386, since the 32-bit hypervisor is not supported any
      more and we can't build livepatches for it either.
    
    After this, the xen/test subdirectory is somewhere were make can be
    invoked in the way which is conventional for xen.git/xen/ subdirs.
    
    None of this is yet invoked from the top-level Makefile.
