I'm fine with not supporting things.  But I'm pretty stupid here.  Is
this just not supporting some old chip?  Or is this some ABI that a new
chip could have both and can switch at run time?  If the latter, we need
to support it.  If the former, and hints on how to make sure you can't
build audit with OABI?

My current hack in the kernel is to change the Kconfig entries for audit. As
for userspace, I guess you have to check the toolchain triplet somehow. v6
onwards makes use only of EABI and it's becoming increasingly more difficult
to find distributions supporting OABI (required for CPUs prior to v4t).

I'll followup with an email explaining ARM ABIs to help out - might take
me a bit of time to get to it.
