No luck.  That gets .db files from share into the O.<arch> directory, but it's
tough sledding from there, because make is frantic about dependencies on
.db files in that directory.

I ended up with something that copies straight from share into the install
directory and is derived your code involving the symbol TEMPLATE_LINKS.
The user specifies the new symbol DB_LINKS in Makefile.Host, like so

	DB_LINKS += $(SHARE)/stdApp/Db/motor.db

and this gets treated by the following lines added to RULES.Db

	ifneq '$(DB_LINKS)' ''
	build:: $(notdir $(DB_LINKS))
	endif

	$(notdir $(DB_LINKS)):
		@$(RM) $(addprefix $(INSTALL_DB)/, $(notdir $(DB_LINKS)))
	ifndef WIN32
		ln -s $(DB_LINKS) $(INSTALL_DB)
	else
		$(CP) $(DB_LINKS) $(INSTALL_DB)
	endif

This works and doesn't appear to have any side effects.

I also have modified copies of dbLoadRecords and dbLoadTemplate so that
they work with a path argument, and are backward compatible with the standard
calling syntax.
