I am not so much concerned about bugs, as much as the case that we ship a build that works for some but not for most (too easy to do by picking eg. sm_30 as build target); that would not be exactly a bug but still good enough of a reason for deprecating a certain type of build (or, providing an alternative, OK) or changing the default - although with modulefiles only the last one gets picked.

Finally, we may always meet difficult to catch issues down the road, eg. like the following example:
```
**  The routine cublasCsyrk() may produce incorrect results on GPUs that implement 
the sm_30 architecture when the size of matrix parameter A exceeds (128M - 512) 
total elements.  
```

But, if we feel confident on the testing aspect of the easyconfig, there is only a no-op for my commenting...
