d2 etc: disable OABI compat

Commit fefc65c201fc50bd4f22602292bbf48c8df23450 removed the requirement
for OABI compatibility back in April due to TLB crashes, but we still
have it on. I have personally seen these crashes. KILLITWITHFIRE.

The switch from ABI to EABI occurred before Android even existed. There
is no reason to preserve compatibility with binaries we never had.
