Can't compile v6.2-rc1 kernel rpm in openSUSE

[Guoqing Jiang <guoqing.jiang@xxxxxxxxx>]

Hi,

With latest v6.2-rc1, I can't compile kernel rpm in openSUSE leap.

linux> make rpm-pkg -j16

Seems the below change in commit 8818039f959b("kbuild: add ability
to make source rpm buildable using koji") caused the issue.

Because the relevant package name in openSUSE is libelf-devel as
mentioned in ./tools/perf/Makefile.config

Please install libelf-dev, libelf-devel or elfutils-libelf-devel


Thanks,
