Yes, it would.

Realising that I'm pushing my luck, I would warmly encourage you to do
another 10.x release.
Partially due to the severity of the bug - anything built with -m32 is
affected - and partially due to how wide-spread the 10.x series is.

From a casual look at repology [1] the following distributions are
affected and a bunch of them will be "stuck" with the 10.x series.
Thus I do think it will be of great benefit in having another 10.x
with said fix - even if only this patch is included.

List of distributions using GDB 10.x alongside 5.9+ kernel - Alpine,
Arch, Debian testing, Fedora 33&34, openSUSE Leap 15.x, Ubuntu 21.04
... and their respective derivatives.

Thanks for your time and dedication improving GDB.
