CRIS: Update main Kbuild makefile.
- Remove old and non-generic targets, use generic ones instead. - Add sub-arch as mach-fs or mach-a3 for EtraxFS and Artpec-3 respectively. - Add links to sub-arch directories, and erase before trying to create them. - Include from sub-arch specific include directory "mach". - Add files to be cleaned in CLEAN_FILES instead of as archclean target.
