Here is what I propose we check in.  I can't test it at the moment,
because we've suffered a massive power outage and we're still working
on getting every machine back up. I'm fairly confident, though.

Rather than remove the check, I added an assertion. That's because
eventually I want to add an extra check, for Lynx178. On the GDB side,
the Lynx178 port is roughly a bareboard powerpc configuration. But
it is using XCOFF, and I wanted to make sure that we'd never match
a Lynx178 binary with the AIX ABI. To do that, I use a BFD/XCOFF
function, so I thought adding the explict assertion would help.

While at it, I added a function description, that explicitly mentions
the pre-condition/assertion.

If there are no objections, I will commit the attached patch within
the next few days, after being able to test on AIX again.

Thanks,
