RFR (M): 8024265: Enable new build on AIX (top level part)

Hi Magnus,

thanks for doing "JDK-8024665 Move open changes for JDK-8020411 to
closed source"!

Can you now please give Vladimir the GO signal (from a
build-perspective) to integrate my changes (from
http://cr.openjdk.java.net/~simonis/webrevs/8024265.v4/) into the
ppc-aix-port/stage repository?

Actually my changes revert 8020411 as well. This means that when
8024665 will flow into our staging repository, we would have to
manually resolve platform.m4 to our version which we checked in, but
that should be OK.

I'd really appreciate if we could push my change now, otherwise we
would have to wait another couple of weeks until 8024665 goes from
build -> main -> stage.

Thank you and best regards,
