Some versions of GCC require insane (>2GB) amounts of memory
to compile translate.o. As a countermeasure, compile it
with -O1. This should fix the buildbot failure for
default_x86_64_fedora16.

to compile translate.o. As a countermeasure, compile it
with -O1. This should fix the buildbot failure for
