clean:

+ rm -f yaffs_tester $(ALLOBJS) core $(SYMLINKS) log.txt
This yaffs_tester testes the bug "error code 0, when yaffs has run out of handles"
the yaffs_tester program may crash with another error before running out of handles.
-To fix this make clean the to reseed the rand function producing random names.
+To fix this use remove the emkfile and use the seed 1288065181
+./yaffs_tester -seed 1288065181
