Subject[PATCH 3/9] kbuild: rpm-pkg: clean up mkspec
Clean up the mkspec without changing the behavior.

- grep CONFIG_DRM=y more simply

- move "EXCLUDE" out of the "%install" section because it can be
computed when the spec file is generated

- remove "BuildRoot:" field, which is now redundant

- do not mkdir $RPM_BUILD_ROOT/lib/modules explicitly because it
is automatically created by "make modules_install"

- exclude "%package devel" from source package spec file because
it does not make sense where "%files devel" is already excluded

- exclude "%build" from source package spec file

- remove unneeded "make clean" because we had already cleaned
before making tar file

- merge two %ifarch ia64 conditionals

- replace KBUILD_IMAGE with direct use of $(make image_name)

- remove trailing empty line from the spec file
