Do these additional build targets actually result in build breakage?

I'm not sure if anyone does run-time testing on build-many-glibcs.py
output.

I would rather suggest adding an -O3 targets (maybe s390x due to its
inliner differences, and x86-64), where we know we have occasional build
breakage.

Thanks,
