Open ppc/s390/aix issues

[Lindenmaier, Goetz]

Hi,

We are now working on the ppc/s390/aix ports for quite some years.
With the release of jdk11 we delivered a very comprehensive and well 
maintained port I think. For example, the jdk and hotspot jtreg tests
can be run quite stable on these platforms. 

I filed bugs for all the remaining issues we see, at least in the 
test setup we run at SAP.

Everybody is invited to join in and fix these few finally :)
