Nothing in the makefiles adds the dependency of foo.o against (typically)
foo.c when the foo.o list is generated.
This means that makes suffix rules are used to find the source file (as
well as the commands).
A simple change to the relevant .mk file would fix this - and also
fix the problem in libc where some sub-archs don't want the .S file.
