vmlinux.bz2 was added to the rpm packages in 2009 in the
fc370ecfdb ("kbuild: add vmlinux to kernel rpm") but seemingly hasn't
been used since.
Originally this should have been split up in a seperate debugging
package because it massively increases the size of the generated rpm's
e.g. kernel rpm built using binrpm-pkg on Fedora 36 default 5.19.8 kernel
config and localmodconfig is ~255MB with vmlinux.bz2 and only ~65MB
without it.
Make the kernel built rpms about 4x smaller by not including the unused
vmlinux.bz2 in them.

By default, 'buildroot' contains %{_arch} (see /usr/lib/rpm/macros).
_arch is generally defined in /usr/lib/rpm/platforms/*/macros, where
the platform sub-directory is specified by --target= option for cross
builds.
If the given arch does not exist, %{_arch} is not expanded.
In the example above, --target=arm is passed to rpmbuild, but
/usr/lib/rpm/platforms/arm-linux/ does not exist.
The '%' character in the path confuses GNU make and rpmbuild.
The same occurs for such architectures as csky, microblaze, nios2, etc.
Define _arch if it has not been defined.

These have been required by the Debian policy for a while, even though
the tooling can detect and workaround their omission, but are a hard
requirement when using rootless builds.
[masahiro:
The following Debian policy is particularly important for rootless builds:
"Both binary-* targets should depend on the build target, or on the
appropriate build-arch or build-indep target, so that the package is
built if it has not been already."

There was a request to preprocess the module linker script like we
do for the vmlinux one. (https://lkml.org/lkml/2020/8/21/512)
The difference between vmlinux.lds and module.lds is that the latter
is needed for external module builds, thus must be cleaned up by
'make mrproper' instead of 'make clean'. Also, it must be created
by 'make modules_prepare'.
You cannot put it in arch/$(SRCARCH)/kernel/, which is cleaned up by
'make clean'. I moved arch/$(SRCARCH)/kernel/module.lds to
arch/$(SRCARCH)/include/asm/module.lds.h, which is included from
scripts/module.lds.S.
scripts/module.lds is fine because 'make clean' keeps all the
build artifacts under scripts/.
You can add arch-specific sections in <asm/module.lds.h>.

Redefine GZIP, BZIP2, LZOP variables as KGZIP, KBZIP2, KLZOP resp.
GZIP, BZIP2, LZOP env variables are reserved by the tools. The original
attempt to redefine them internally doesn't work in makefiles/scripts
intercall scenarios, e.g., "make GZIP=gzip bindeb-pkg" and results in
broken builds. There can be other broken build commands because of this,
so the universal solution is to use non-reserved env variables for the
compression tools.

Allow user to use alternative implementations of compression tools,
such as pigz, pbzip2, pxz. For example, multi-threaded tools to
speed up the build:
$ make GZIP=pigz BZIP2=pbzip2
Variables _GZIP, _BZIP2, _LZOP are used internally because original env
vars are reserved by the tools. The use of GZIP in gzip tool is obsolete
since 2015. However, alternative implementations (e.g., pigz) still rely
on it. BZIP2, BZIP, LZOP vars are not obsolescent.
The credit goes to @grsecurity.
As a sidenote, for multi-threaded lzma, xz compression one can use:
$ export XZ_OPT="--threads=0"
