Thanks for the patch. I've changed it a bit -- after thinking about it
for a *long* time (!), experimenting with Gnu ld, and working through
a few other test cases, I've decided that linker-generated sections
should match *only* via the output section name (except for the case
of /DISCARD/). Accordingly, this patch just changes
Output_section_definition::output_section_name() to check the output
section name for a linker-generated section. I think this will also
fix both PR 20062 and PR 20522, as we will no longer try to place
.rela.data into .rela.dyn.

I've attached the patch as committed.
