The Makefile of the s390-ccw bios does not handle dependencies of the *.c files from the headers yet, so that you often have to run a "make clean" to get the build right when one of the headers has been changed. Let's make sure that we generate and include dependency files for all *.c files now to avoid this problem in the future.
