Description Mark Wielaard 2024-04-13 10:23:43 UTC 
find-debuginfo thinks the BPF files are "normal" ELF files and calls gdb-add-index on them. But the BPF files aren't "normal" and don't have any debuginfo. So gdb-add-index fails.

See e.g. https://kojipkgs.fedoraproject.org//packages/kernel/6.8.5/301.fc40/data/logs/x86_64/build.log
