Well, only if we want to keep the crosstests from failing.
```
shader_runner:1237: Running tests from a Windows cross build

shader_runner:95: Driver string: d3d10warp.dll.

shader_runner:73: Section [test], line 28: Test failed: Failed to compile shader, hr 0x80004005.
```

Ideally we would be able to specify

```
[require]
shader model >= 2.1
```
