I don't know.  But I also don't want to have 'make modules_install
install' on an arch without an install target appear to work, so I
don't know how to do it in the kbuild core.  That is, I don't want to
define an install target; I just want to add a dependency if the
target is already there.

Also, this patch has a repeated ifneq.  I'll fix it in v2.
