Currently xtensa uses 'zImage' as a synonym of 'all', but in fact xtensa supports three targets: 'Image' (ELF image with reset vector), 'zImage' (compressed redboot image) and 'uImage' (U-Boot image). Provide separate 'Image', 'zImage' and 'uImage' make targets that only build corresponding image type. Make 'all' build all images appropriate for a platform.
