Here's what happened:
- You started the thing and the kernel compile complained about an unclean tree. - You ran mrproper. - You tried to run the thing again.
amirite?
If so, what happened is that mrproper deleted the .o files from the toolchain. Solution:
ARCH=powerpc make -C tools/testing/selftests/wireguard/qemu -j$(nproc) clean ARCH=powerpc make -C tools/testing/selftests/wireguard/qemu -j$(nproc)
Let me know how that goes.
