RFR: JDK-8256922: ppc, ppcle build broken after JDK-8254231 [v3]

[Thomas Stuefe]

> Hi,
> 
> may I please have reviews for these fixes to the ppc, ppcle builds after JDK-8254231.
> 
> Once the build is fixed, VM does not come up, but that is a separate issue (JDK-8256924).
> 
> This roughly followed Alekseys work on s390, but additionally I had to rename the _abi macro due to name conflict with a class member in the new code.
> 
> Thanks, Thomas
