The section is described here: https://refspecs.linuxfoundation.org/LSB_1.3.0/gLSB/gLSB/symverrqmts.html Patch just teaches obj2yaml/yaml2obj to dump and parse such sections. We did the finalization of string tables very late, and I had to move the logic to make it a bit earlier. That was needed in this patch since .gnu.version_r adds strings to .dynstr. This might also be useful for implementing other special sections. Everything else changed in this patch seems to be straightforward.
