They are just .o's really. It is presumably faster to do one step per final .ko rather than many tiny ones (per source file). That might be a benefit to doing it all at the end for vmlinux too. I think the best way would be to have a vmlinux.o that we actually use in the link, rather than just analyzing and discarding. Then you can just do your existing hack on vmlinux.o before it's linked into vmlinux.
