This is with defconfig, CONFIG_KASAN=y, CONFIG_KUNIT=y, and
CONFIG_KUNIT_ALL_TESTS=y. To reproduce,

tuxmake \
  --runtime podman \
  --target-arch arm64 \
  --toolchain gcc-13 \
  --kconfig defconfig \
  --kconfig-add CONFIG_KASAN=y \
  --kconfig-add CONFIG_KUNIT=y \
  --kconfig-add CONFIG_KUNIT_ALL_TESTS=y
