This change (i.e. deleting %buildroot tree at the beginning of %install)
comes from the change in redhat-rpm-config 
(see $ rpm -q --changelog redhat-rpm-config and the file /usr/lib/rpm/redhat/macros )

Recent kernel.spec has the following lines at the top to prevent this
behavior.
-------------------------------------------------------------------
# We have to override the new %%install behavior because, well... the kernel is special.
%global __spec_install_pre %{___build_pre}
-------------------------------------------------------------------
