There is a check, hence the 'if [ "" != "" ] ...' part. But the shell
seems to be complaining about being unable to parse the command even
though it isn't going to execute it.

The command in question is the last one for the "clean" target in
Rules.make:

clean:
	-rm -rf $(OBJDIR) $(EXTRA_CLEAN_DIRS)
	-rm -f $(EXTRA_CLEAN_FILES) *.tmp.html
	-if [ "$(CLEAN_SUBDIRS)" != "" ] ; then \
		for dir in $(CLEAN_SUBDIRS) ; do \
			$(MAKE) -C $$dir clean ; \
		done ; \
	fi
