So I think that for the problems related to building the kernel with gcc
11 in Fedora Rawhide using the default that is now DWARF5, pahole 1.20
is good to go and I'll tag it now.

dwarves-1.20-1.fc34.x86_64
libdwarves1-1.20-1.fc34.x86_64

Fixes both "failed to validate module [?????] BTF: -22" type errors,
and 'in-kernel BTF is malformed" with qemu-kvm and libvirt.

Is that expected? Or maybe the second issue was fixed by
gcc-11.0.0-0.18.fc34.x86_64 [(GCC) 11.0.0 20210130]? This is what I
get for changing more than one thing at once.
