The original line changed in Maxims latest patchset to:

	-u $(call getschemeplusuri,$(BR2_PRIMARY_SITE)/$(notdir $($(PKG)_DL_DIR)),urlencode) \

would the following line be the correct improved change?

	-u $(if $(PKG),$(call getschemeplusuri,$(BR2_PRIMARY_SITE)/$(notdir $($(PKG)_DL_DIR)),urlencode)) \
