I went looking for how to link with a setting for DT_RUNPATH rather than DT_RPATH, and came up blank in the ld doc and a web search initially. I eventually came across a post which mentioned using --enable-new-dtags, but there's no way I'd have got that without reading the source, with no indication what "the new dynamic tags" are that it controls. I suggest listing those tags with index entries to be explicit that you need --enable-new-dtags with --rpath for that job, at least. I assume there are others to treat similarly.
