This will allow "clean" to work from an out-of-tree build when it will be available. Some of the file been removed in current "clean" target aren't added to $(clean-files) because they are already listed in $(extra-) or $(extra-y). Also clean files in "arch/x86/boot" from that directory by allowing "clean" to descend into the subdir by adding "boot" into $(subdir-).
