One way:
ifneq (,$(WORK_DIR))

ifeq (1,$(words $(wildcard $(WORK_DIR)))

You could implement that using $(filter) or $(filter-out) to strip the
TOP_DIR part of WORK_DIR (i never remember which filter func does what), and
then check for $(TOP_DIR)/whateverIsLeftOver. Perhaps $(dir) and/or
$(notdir) would be appropriate.
But there are probably simpler ways to do those things. Let's wait and see
what the Gurus can tell us...
