I posted a patch here
https://sourceware.org/pipermail/binutils/2021-March/115863.html
It's been tested with gdb, sim and binutils builds.

Tom offered to solve the problem himself, so I'm waiting on that or
for someone in the gdb camp to review my patch.  Since I messed this
up in the first place by taking a comment by Tom as a go-ahead rather
than first posting a patch for proper review by gdb maintainers, I'm
being a little cautious in committing the above patch.
