The dt_binding_check target is located outside of the 'ifneq ($(dtstree),) ... endif' block. Hence, you can run 'make dt_binding_check' on any architecture. This makes a perfect sense because the dt-schema is arch-agnostic. The only one problem I see is that scripts/dtc/dtc is not always built. For example, ARCH=x86 defconfig does not define CONFIG_DTC. Kbuild descends into scripts/dtc/, but does nothing. Then, it fails to build *.example.dt.yaml files. Let's build scripts/dtc/dtc forcibly when running dt_binding_check. The dt-schema does not depend on any CONFIG option either, so you should be able to run dt_binding_check without the .config file. Going forward, you can directly run 'make dt_binding_check' in a pristine source tree.
