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.

%description headers
|
|
Kernel-headers includes the C header files that specify the interface
|
|
between the Linux kernel and userspace libraries and programs. The
|
|
header files define structures and constants that are needed for
|
|
building most standard programs and are also needed for rebuilding the
|
|
glibc package.
