This is just the way Debian names its kernel packages.

And so on. It just happens that this kernel is based on v6.0.10.
$ uname -r 6.0.0-5-powerpc64le
So they are the correct config files.
Also, the mail I replied to talked about checking /sys/kernel/bpf/ (not btf) :-(
still on my build machine (of course):
$ ls -l /sys/kernel/btf/ ls: cannot access '/sys/kernel/btf/': No such file or directory
So it seems that Debian do not build their powerpcle kernels with CONFIG_DEBUG_INFO_BTF. I don't know why not since all the dependencies seem to be OK.
