Presumably the name of this option needs to be changed.
KERNEL_LINUX_CUSTOM_LOCATION or something like that.

Something like:

HOST_CROSSTOOL_NG_DEPENDENCIES = host-gawk host-automake $(if $(BR2_CCACHE),host-ccache)

ifeq ($(BR2_TOOLCHAIN_CTNG_BUILDROOT_KERNEL),y)
HOST_CROSSTOOL_NG_DEPENDENCIES += linux-configure
endif

Would be a lot better.

Missing:

	depends on BR2_LINUX_KERNEL

$(LINUX_DIR) ?
