Would it make sense to have $LOCAL_LIBS as a dependency for the DLLIB 
and STATIC_LIB targets as show below?

$(DLLIB): $(OBJS) $(LOCAL_LIBS)
   @-$(RM) $@
   $(LDSHARED) $(DLDFLAGS) $(LIBPATH) -o $(DLLIB) $(OBJS) $(LOCAL_LIBS) 
$(LIBS)

$(STATIC_LIB): $(OBJS) $(LOCAL_LIBS)
   $(AR) cru $@ $(OBJS)
   @-ranlib $(DLLIB) 2> /dev/null || true

The advantages I see are that make will rebuild the target if one of 
the local libs is updated.  Also the user can add make rules for the 
local libs in "depends".

This may break some peoples extensions though.  (But I don't think many 
people use $LOCAL_LIBS.)
