SAP changes to jdk for Aix

[Lindenmaier, Goetz]

Hi,

I uploaded a webrev with the changes by SAP to the jdk to port it to Aix
to http://cr.openjdk.java.net/~goetz/sap_aix_jdk_changes/.

I diffed the source code of our VM and jdk7u3, sorted out the Aix stuff added
by us, and applied that to our ppc-aix branch.  So this should contain whatever is
necessary for an Aix port, but it will not compile.  I also assume there are
some dependencies to our other changes to the VM which are not included.
If there is something important missing, just tell me and I’ll add it if possible.

Most of our changes are marked with a comment  ‘// SAPJVM’.  We remove these
comments in the code we will submit to our port, but here I left them in, as
I think it’s better to read that way.

The code should work with xlc8, xlc10, Aix 5.2 and up, and as400/pase.

Best regards,
  Goetz.
