Correctly written Driver tests do not depend on any particular target. All Driver code relevant to all targets is present in all cases.

Exactly one test (out of 133) was failing on exactly two bots. I'm not saying what I did was the best thing; it was expedient, to get the bots green again while minimizing the hosts where the test would not run.

If you can show me the code path that is causing the failure, I can probably make a more appropriate change. But again, it does not depend on the target. The test is working fine on every other bot; it does not depend on having the X86 target present.
