Some versions of GCC require insane (>2GB) amounts of memory to compile
translate.o. As a countermeasure, disable the culprit optimization pass.
This should fix the buildbot failure for default_x86_64_fedora16.
Anyway is a good thing to do because people will try to compile 1.3 with
less than 2GB of memory and complain.
