The way we tried to mitigate this in the past was to use -target=aarch64-arm-none-eabi for our downstream compiler, and have downstream differences gated on the arm vendor. It can help keep the upstream tests the same if they use -target=aarch64-unknown-linux-gnu, and have downstream tests checking only the differences.

That was an embedded compiler, so the triples might have been easier to change.
