I didn't follow this particular review closely as Magnus was on it and 
so I had missed the NativeCompilation part. It's true that it is very 
unlikely to be part of the problem described in this bug, but I still 
feel that the safest action at this point is to restore the behavior of 
"external" and "zipped" to what they used to be. Magnus is working on a 
complete fix where debug symbols will be enabled for everything in

Rolling back will be much more work for me than submitting this patch. 
There are two changes already that depend on this change. I also don't 
dislike the idea of the new configure parameter.

I hope you won't object to me pushing this with just ihse as reviewer. I 
feel this is rather a priority to get fixed.
