I made a recipe for kconfig-hardened-check-native, copied from the board/qemu config.gz, cmdline.txt, sysctl.txt and ran:

$ oe-run-native kconfig-hardened-check-native kernel-hardening-checker -c /workdir/hardening/config.gz -l /workdir/hardening/cmdline.txt -s /workdir/hardening/sysctl.txt
Getting sysroot...
