.relr.dyn, binutils 2.37 and glibc 2.36

I have seen lots of stuff float by on the glibc and binutils list about
changes to each related to relocations.  My I've lost track of what
changes have been made.  I am not sure if this should be posted to
the glibc list or here, so I am trying here first instead of cross posting.

I have a colleague that is using a glibc 2.36 based system and is
using binutils 2.37 (one that I built from source, not the system ld).

This is the error he gets

/opt/binutils-2.37/bin/ld: /lib64/libc.so.6: unknown type [0x13] section
`.relr.dyn'

But then he follows up that while ld.bfd doesn't work, ld.gold (i.e.,
-fuse-ld=gold)
does work.

My recollection is that the changes made in the newer versions of glibc for
relocations required a newer binutils (2.38, I think).

So, what binutils should we be using?  And why, with 2.37, does ld.bfd
croak,
but ld.gold does not?

And yes, I know, if it is a really new system, we should be using the system
binutils for compatibility.  Doing things from source is a vestige of the
fact that
our automated build machine is ancient, so a lot of our tool chain is built
from
source.

Thanks and regards,
