Unfortunately it breaks:

I did a make clean without telling make ARCH=arm just prior, so
arch/arm/boot/compressed contains some stale files.  It looks like
there's a missing dependency on the top level vmlinux file:

-rwxrwxr-x    1 rmk      rmk       1822788 Nov  4 15:37 arch/arm/boot/compressed/piggy
-rwxrwxr-x    1 rmk      rmk       2283887 Nov  4 21:18 vmlinux

but oddly, arch/arm/boot/compressed/Makefile contains:

$(obj)/piggy:    vmlinux;       $(call if_changed,objcopy)
