Do we really need a helper script to do this?
NETWORK_IFACES = $(TARGET_DIR)/etc/network/interfaces
NETWORK_DHCP_IFACE = $(call qstrip,$(BR2_SIMPLE_DHCP_INTERFACE))
define NETWORK_ADD_DHCP_INTERFACE
echo "auto $(NETWORK_DHCP_IFACE)" >> $(NETWORK_IFACES)
echo "iface $(NETWORK_DHCP_IFACE) inet dhcp" >> $(NETWORK_IFACES)
endef
define NETWORK_CREATE_IFACES_FILE
rm -f $(NETWORK_IFACES)
echo "auto lo" >> $(NETWORK_IFACES)
echo "iface lo inet loopback" >> $(NETWORK_IFACES)
$(NETWORK_ADD_DHCP_INTERFACE)
endef
TARGET_FINALIZE_HOOKS += NETWORK_CREATE_IFACES_FILE

Why two options? Just make the BR2_SIMPLE_DHCP_INTERFACE empty by
default (does nothing), and when non-empty, used as the DHCP network
interface.
