This is how I tested it on Linux next tag: next-20230516. Installed
tuxmake [1], and tuxrun [2].

$ tuxmake --runtime podman --target-arch arm --toolchain gcc-12 \
 --kconfig defconfig \
 --kconfig-add https://raw.githubusercontent.com/Linaro/meta-lkft/kirkstone/meta/recipes-kernel/linux/files/lkft.config \
 --kconfig-add https://raw.githubusercontent.com/Linaro/meta-lkft/kirkstone/meta/recipes-kernel/linux/files/systemd.config \

 --kconfig-add CONFIG_OF=y --kconfig-add CONFIG_SYN_COOKIES=y--kconfig-add CONFIG_SCHEDSTATS=y --kconfig-add CONFIG_AHCI_DWC=y \
 dtbs dtbs-legacy headers kernel kselftest modules \
 --results-hook "tuxrun --runtime podman --device qemu-armv7 --boot-args rw --tuxmake ./ --rootfs https://storage.tuxboot.com/debian/bookworm/armhf/rootfs.ext4.xz --parameters SKIPFILE=skipfile-lkft.yaml --parameters KSELFTEST='\$BUILD'/kselftest.tar.xz --tests kselftest-mincore --timeouts boot=30"
