OpenJDK7 port to the little endian PowerPC64

[Volker Simonis]

Hi Alexander,

and there's one thing I forgot - you have to sign the Oracle
Contribution Agreement (OCA,
http://www.oracle.com/technetwork/oca-405177.pdf) before we can check
in your contributions.

As far as I can see, you're not on the list of the current signatories
(http://www.oracle.com/technetwork/community/oca-486395.html) and
Google only signed the OCA for a specific set of people which doesn't
include you.

Regards,
Volker
