I had the same expectation and it was a sad day when I found myself
having to do it manually in the out of tree makefile, having to handle
__user annotations in particular, as it wasn't possible to call
scripts/headers_install.sh as scripts/unifdef.c wasn't compiled and
available in the various kernel build environment provided by
distribution packages.

PS: please, don't top post reply, thanks.
