Yes. But with my proposed solution any new platform may easily add
itself to the list of platforms which don't have the SA-agent.

I don't quite understand. If a platform doesn't support the SA-agent
there's no need for any error checking. This fix doesn't change the
behaviour on any other platform except for aix-ppc64 and ZERO. Any
other platforms which don't support the SA just add themselves to the
lisst in the if-statement without affecting the other platforms.

OK fine. I've added one more tiny fix which was needed to build on
AIX. It's in an if-def AIX anyway, so it won't impact other platforms.
It just fixes the location of the static version of libjli:

OK to push now?

Thanks,
Volker
