DT_RPATH is just as useful as it always was for testing purposes, when 
you're building binaries against a sysroot and use -rpath and 
-dynamic-linker pointing to that sysroot, and you really do want the RPATH 
used at runtime to find both direct and indirect dependencies and 
DT_RUNPATH would *not* serve the same purpose (because the sysroot is 
intended to have exactly the same binaries that would eventually be used 
in the root filesystem of the target in production, it would not be 
appropriate to set DT_RUNPATH in any of those binaries).
