[Aleksei Voitylov]

Hi,

please review this low risk fix that re-enables C2-only VM build for 
AARCH64.

webrev: 
http://cr.openjdk.java.net/~dchuyko/aleksei.voitylov/8207240/webrev.00
bug: https://bugs.openjdk.java.net/browse/JDK-8207240

Testing: VM built this way passed jtreg hotspot tests in fastdebug mode.

OK for 11?

Thanks,
