OK.

I actually think my changes are pretty clean, but obviously if you can
do better that's terrific!

The current code "lies" about AIX in that it says if *at ltconfig-time*
you said:

  --enable-shared

Then you really meant:

  --enable-shared --disable-static

But, you didn't.  You just said --enable-shared, and you want static
libraries just like everyone else.  It's just that your system treats
a shared library like a static archive, too.

So, I changed it to have an explicit variable that says "my system
works like AIX -- both libraries are folded into one."

Then, if you actually try to *build* both libraries at the same time
with libtool, it says "oh, look, on this sytem I only need to build
the shared variant, and I get the static one for free."

This approach admits freely that AIX is not a SVR4-ish system in this
regard.  (The old approach tried to pretend that it was, but that you
never wanted static libraries.)  As with good machine descriptions, I
think we should just be honest: AIX is "weird" relative to GNU/Linux,
Solaris, IRIX, etc.  We just have to go with it. :-)
