```
* Fat builds are enabled by default on the architectures where
	  it is supported (x86_64, arm and powerpc64). To disable
	  runtime selection, and instead specify the processor flavor
	  at configure time, you need to pass --disable-fat to the
	  configure script.
```

So we might want to be sure about how well that's working first, before merging.
