Subject: Regression with patch "kbuild: rpm-pkg: Generate debuginfo package manually"

I noticed with the recent patch below:

    commit 62089b804895e845f82e132ea9d46a1fc53ed5a7
    Author: Nathan Chancellor <nathan@...nel.org>
    Date:   Wed Jan 21 15:29:15 2026 -0700

       kbuild: rpm-pkg: Generate debuginfo package manually

that all of our test builds were failing to build kernel RPMs for
6.19-rc8 and later (see e.g.
http://smb311-linux-testing.southcentralus.cloudapp.azure.com/#/builders/1/builds/99/steps/9/logs/stdio).
See below:

This is building kernel rpms on a RHEL9.7 system to be copied over to
our Fedora test VMs. The kernel build works fine but the rpm packaging
now fails. Works fine for 6.19-rc7 (or 6.19-rc8 with this commit
reverted) but fails on 6.19-rc8.

Any idea how to fix this build regression.
