+We've seen reproducibility failures where it appears an extra -O3 compiler flag ends
+up in the multiarray library compilation. This can only really have come through
+extra_info since it only affects just this library. Rather than try and track
+down exactly where this came from in a rabbit warren of code, just disable
+this since we don't have any of the dependencies.
