`lscpu`: panic on aarch64-linux

[RossComputerGuy]

I'm running uutils-util-linux inside of an initrd in an Arm QEMU VM on an Ampere Altra host. util-linux is built from commit 93a60ee, lscpu fails with a panic:

$ lscpu

thread 'main' (161) panicked at src/uu/lscpu/src/sysfs.rs:154:71:
called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

/sys is mounted, I'm not sure what the problem is. lscpu works on my host and other Arm systems. This is how I have QEMU configured:

qemu-system-aarch64 -drive if=pflash,format=raw,unit=0,readonly=on,file=$(nix build nixpkgs#OVMF.fd --no-link --print-out-paths)/FV/AAVMF_CODE.fd -machine virt,gic-version=max,accel=kvm:tcg -cpu max -drive file=fat:rw:fs,format=raw,media=disk -display none -serial stdio -m 128G -smp 16 -device virtio-gpu
