I remember something similar ages ago with another IPv6 symbol no being
pulled in - can't remember how to fix it.

For in6addr_loopback, like this, in arch/um/Makefile:

CFLAGS += $(CFLAGS-y) -D__arch_um__ -DSUBARCH=\"$(SUBARCH)\"	\
	$(ARCH_INCLUDE) $(MODE_INCLUDE) -Dvmap=kernel_vmap	\
	-Din6addr_loopback=kernel_in6addr_loopback
