    git-kernel: $(SUBDIR) should always be $(LINUX_VERSION)
    
    Before SUBDIR was set to $(PATCHVER) which may
    or may not include the minor version number of
    the linux kernel version. Usually it doesn't.
    
    So the git-clone'd linux kernel was packed without
    the minor version number taken into account, which
    broke further processing, as it expected the
    extracted dir being named linux-$(LINUX_VERSION)
    (=with minor version) rather than linux-$(PATCHVER)
    (=without minor version).
    
    Changing SUBDIR to $(LINUX_VERSION) creates
    consistent behaviour here.
