After 144c5b6d58803a2d4a0fe92a0fe331ff0347dc3b, we still see this test running in CI for aarch64-linux targets. This appears to be related to the triple being `aarch64-unknown-linux-gnu`, or similar.

The bot link below includes 144c5b6d58803a2d4a0fe92a0fe331ff0347dc3b, and fails the deep-recursion.c test, which should have been disabled. https://luci-milo.appspot.com/ui/p/fuchsia/builders/toolchain.ci/clang-linux-arm64/b8767065085790662609/overview
