Thanks for reviewing the change.

I'll wait a review for PPC64. However I'm a little bit confused since the
webrev I provide will, when applied to 8u, add aarch64 as well which is not
currently in the 8u forest (maybe who pushes it could trim it off or use the
previous webrev)...

... and maybe Andrew's reply (since he just added the aarch64-port-dev ML) was
just for aarch64-port folks and I got it wrong... (it seems the case...)

Please advise.
