RFR(S): JDK-8031134 : PPC64: implement printing on AIX

[Volker Simonis]

Hi,

could somebody please review the following small change:

http://cr.openjdk.java.net/~simonis/webrevs/8031134/

It's the straight forward implementation of the basic printing
infrastructure on AIX and shouldn't have any impact on the existing
platforms. As always, this change is intended for the
http://hg.openjdk.java.net/ppc-aix-port/stage/jdk repository.

Thank you and best regards,
Volker
