This needs to be on an arm64 machine.
The outline-atomics flag does not exist when targeting x86_64.
The flag has been back-ported to Ubuntu 20.04 a year and a half ago: IIRC, it went in just before the release in April 2020.

I have not re-compiled gcc.  The gcc-9.3 is the one distributed as part of Ubuntu 20.04.

If you need access to Graviton2 instances, we have a system of credits that we can use to fund compute time for open-source CI projects.
Let me know if you are interested in getting those compute credits, and I will take the request to my management.
