Sorry, David. I have been meaning to work on that ever since
we talked about it...

I spent some time today isolating the patches. I am currently
testing the patches we wrote for support on AIX 5.3. I then see
a few more patches to extend support to AIX 7.1 - section alignment
constraints, and stuff related to TLS.

Just for anyone who is curious, this is what I am testing.
It is missing the pieces for the other tools such as objdump,
for instance. But I think those can be submitted separately.

It might not apply to HEAD just yet, because I'm going at it
step by step. For those who use git, I applied it on top of:
