[11] RFR (XS) 8207047: Multiple VM variants build fail

[Boris Ulasevich]

Hi all,

Please review a simple patch:
http://cr.openjdk.java.net/~bulasevich/8207047/webrev.00
https://bugs.openjdk.java.net/browse/JDK-8207047

Collision happens on JFR gensrc tool when make system runs several VM 
configuration's gensrc concurrently. Let us move JFR gensrc tools files 
from shared output to the JVM_VARIANT output folder.

thanks,
Boris
