Looks good to me too. Thanks for doing this. I think it should go
on the 2.22 branch as well.

Me neither, unfortunately. But I agree it looks right. There's a
possibility that we could create the dynamic sections before the
definition of __rld_obj_head has been read in (e.g. from the
check_relocs of a previous object). In that case it looks like
we would create the .rld_map section and __rld_map/__RLD_MAP symbol,
then later switch to __rld_obj_head. .rld_map would then be left
at zero size and the __rld_map/__RLD_MAP symbol would be ignored
when setting the tag value. But your patch preserves the
behaviour in that case too.
