If I am reading things correctly, the later one that appears on the list
of headers is respected.

Our respecting of DT_RUNPATH is mostly a hack to deal with upstreams
that do things like read the ELF spec that calls RPATH deprecated.

time until we got an OK to do it, and the time wasted by people not
understanding why random binaries failed to run was staggering.
