We tried such things, but it results in kbuild arguing over building lib1funcs.S in arch/arm/lib and arch/arm/boot/compressed. You end up with it rebuilding the arch/arm/lib one, followed by a rebuild of the arch/arm/boot/compressed one.
We've ended up with what we have because its about the only way to get kbuild to behave.
