I think "make clean" does more than you'd like in that situation. Here
is what it does:

clean:
	rm -rf $(STAGING_DIR) $(TARGET_DIR) $(BINARIES_DIR) $(HOST_DIR) \
		$(STAMP_DIR) $(BUILD_DIR) $(TOOLCHAIN_DIR) $(BASE_DIR)/staging \
		$(TOOLCHAIN_EXTERNAL_DIR)

It takes *everything* except the config and download dir.

I'm just scratching my own itch :-) Glad you like it.

Patch v2 coming soon.
