When U-Boot is enabled and no custom patch directory has been set, then the current test: ifneq ($(strip $(BR2_TARGET_UBOOT_CUSTOM_PATCH_DIR)),"") works. However, when U-Boot is not enabled, but still gets compiled because mkimage is needed to build the kernel, BR2_TARGET_UBOOT_CUSTOM_PATCH_DIR is completely empty. It does not even have quotes. So the test in fact needs to be: ifneq ($(call qstrip,$(BR2_TARGET_UBOOT_CUSTOM_PATCH_DIR)),) Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
