[committed] prune warning from test output to avoid arm-none-eabi failure (PR 83303)

- Subject: [committed] prune warning from test output to avoid arm-none-eabi failure (PR 83303)
- Authentication-results: sourceware.org; auth=none
For reference, I committed r255450 to avoid the test failure
reported on the arm-none-eabi target. The warning is valid
but unrelated to the purpose of the test so I pruned it from
its output.
