pstore-blk contains of two different layers: a) a tiny layer of sugar coating ontop of pstore-zone. This part has no dependencies on the block layer, and can be used e.g. by mtd b) an implementation of a default fallback pstore zone backend for block devices Add an ifdef for the latter so that pstore-blk itself does not have to depend on CONFIG_BLOCK.
