Consider this code using CMake 2.8.11:

 cmake_minimum_required(VERSION 2.8.11)
 #...
 add_library(foo SHARED foo.c)
 target_link_libraries(foo LINK_PUBLIC a)
 set_property(TARGET foo APPEND PROPERTY LINK_INTERFACE_LIBRARIES b)

If someone were to change the first line to require 2.8.12 then
suddenly the link interface will drop "b" silently.

With my suggestion then tll will also populate INTERFACE_LINK_LIBRARIES
if the policy is not set (or a C++-only proxy).  From that the existing
comparison of old and new interface properties will work.
