Add dummy.o to the targets list, and fill targets automatically from $(vmlinuzobjs) to avoid having to maintain two lists. When building with XZ compression copy ashldi3.c to the build directory to use a different object file for the kernel and zboot. Without this the same object file need to be build with different flags which cause a rebuild at every run.
