I'm not sure I understand, do you want to use the OpenCL build option
or do you want to introduce another option? If the already existing
options can be used, we should prefer that rather than makeing the
interface more complex.

Add a third option opencl=auto, which will automatically enable the
opencl path if opencl is available. This allows the user to disable
opencl if she doesn't want it for whatever reason (e.g. in case it
crashes).

Then I'm not against to change the default value to auto.
