RFR: JDK-8210962 Deprecate jdk-variant

Thu Sep 20 16:48:50 UTC 2018

A long time ago, we supported different "variants" of the JDK build, 
like "normal" and "embedded". The --with-jdk-variant and associated 
machinery has been kept in place, even though it's not doing anyting. 
Time to remove it.

I chose to keep the "-normal-" in the build output name so as not to 
break any scripts. But I'm willing to change this if someone has a clear 
opinion otherwise.
