<pre>
    When using `-aux-triple` for an offload target, the incorrect builtins are being exposed. The builtins exposed are not based on the target specified. e.g,
```
static_assert(__has_builtin(__cpuidex), "uh oh");
```
will not fail when given: `-c -fopenmp -Xclang -fopenmp-is-target-device -Xclang -aux-triple -Xclang x86_64-unknown-linux-gnu`, but it should fail because that's a Windows-specific builtin. Removing the `-aux-triple` will cause the assertion to trigger as expected.
