Are you sure the second form actually exists in the rules?  I can't see where 
it is implemented, configure/CONFIG_ADDONS uses $(PROD_$(OS_CLASS)) but 
nothing looks at $(PROD_$(T_A)) that I can see.

Individual applications can (and some do) implement that with something like
  PROD += $(PROD_$(T_A))
but they have to do that explicitly.
