sorry, looks this is confusing to "cp config build_dir/.config" as there's no .config
for this case. We will fix the reproduce step.

Is it possible the lkp-tests is not up to date? the make.cross code was uploaded
recently.

You can try below steps (without the cp .config)
$ mkdir build_dir
$ COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-13.2.0 ~/lkp-tests/kbuild/make.cross W=1 O=build_dir ARCH=arm64 olddefconfig
$ COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-13.2.0 ~/lkp-tests/kbuild/make.cross W=1 O=build_dir ARCH=arm64 SHELL=/bin/bash
Or you can ignore the full make, just do below after make olddefconfig
$ COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-13.2.0 ~/lkp-tests/kbuild/make.cross W=1 O=build_dir ARCH=arm64 SHELL=/bin/bash dtbs_check
e.g.
$ COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-13.2.0 ~/upstream/lkp-tests/kbuild/make.cross W=1 O=build_dir ARCH=arm64 SHELL=/bin/bash dtbs_check 2>&1 | grep 'arch/arm64/boot/dts/renesas/r9a07g043u.dtsi:85.11-94.6'
