Make sure that MACHINE is always assined a sensible value.
MACHINE := sa1100 # Default value to avoid invalid pathnames with no .config
The recursion into the subdirectories does only take care of files listed with EXTRA_TARGETS, host-progs, and clean-files. Only EXTRA_TARGETS are used in the mach- Makefile, and since this is a *.o file it will anyway be deleted by the find that searches the full tree when you do a make clean. Make clean execute a find -name '*.[oas]' and remove all such files, and use the recursion only to take care of other generated files spread out over the kernel src tree.
