Bug#1021236: ortools: Build must be optimized

[Matthias Urlichs]

Source: ortools
Version: 8.2+ds-6
Severity: important
X-Debbugs-Cc: smurf at smurf.noris.de

ORtools needs to be built with optimization enabled.

Otherwise it will (a) be slow and (b) crash when the model cannot be solved
for whatever reason.

Both are pretty bad for production code – as is spewing stderr with
warnings which the user cannot do anything about.
