Initialize LINK_INTERFACE_LIBRARIES target property with a variable 

Define variable CMAKE_LINK_INTERFACE_LIBRARIES to initialize the
value of this property when a target is created.  This allows authors
to write

  set(CMAKE_LINK_INTERFACE_LIBRARIES "")

to disable transitive linking to implementation dependencies of shared
libraries on platforms where it is possible.
