buildroot/utils/genrandconfig
Thomas Petazzoni b07d21ab98 utils/genrandconfig: handle BR2_LINUX_KERNEL_IMAGE_TARGET_CUSTOM=y 
When BR2_LINUX_KERNEL_IMAGE_TARGET_CUSTOM=y,
BR2_LINUX_KERNEL_IMAGE_TARGET_NAME is supposed to be non-empty. But in
the context of genraconfig, we don't know to what value
BR2_LINUX_KERNEL_IMAGE_TARGET_NAME can be set, so let's avoid cases
where BR2_LINUX_KERNEL_IMAGE_TARGET_CUSTOM=y. By dropping this option,
kconfig will revert back to the default image format for the selected
architecture.
