Me too, but that would mean breaking 9.x binaries on 10.x systems, so some thought must be exercised here.

My preference would be to support building eabi binaries only, but have a kernel option that would allow execution of oabi binaries.

Then again, we are also heading to the soft fp vs vfp issue too...
