I realized this might not be clear :-(

This means that when an ioctl() on a process fd results in putting
values into the debugger memory, the results are formatted
as the higher ABI (quoted above) would imply.

And values sent via pointed-to areas (thru ioctl() 
on a process fd) similarly.

It's possible to compile a debugger in any ABI (even o32)
that will debug apps in all 3 ABIs.
