python3-numpy: Attempt to fix reproducibility issue

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 for BLASS support 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 anyway.
