That's true. I think a target for vmlinux.stripped and then use that
in the compressed image targets.

How about this?:

vmlinux.stripped: vmlinux
       cp $< $@
       $(STRIP) $@

vmlinux.gz: vmlinux.stripped

ifndef CONFIG_KGDB
       $(KGZIP) -9c vmlinux.stripped >vmlinux.gz
else
       $(KGZIP) -9c vmlinux >vmlinux.gz
endif

Noted. Will fix for v2.
