Commit0161a94e2d("tools: gpio: Correctly add make dependencies for gpio_utils") added a make rule for gpio-utils-in.o but used $(output) instead of the correct $(OUTPUT) for the output directory, breaking out-of-tree build (O=xx) with the following error: No rule to make target 'out/tools/gpio/gpio-utils-in.o', needed by 'out/tools/gpio/lsgpio-in.o'. Stop. Fix that.
