Hi all,

Please review the patch:

Problem:
'export_optimized_jdk' target specifies ALT_EXPORT_PATH as 
JDK_IMAGE_DIR, as result it exports hotspot to directory for product 
build instead of optimized one.

jbs: https://bugs.openjdk.java.net/browse/JDK-8056223
testing: jprt w/ support of optimized build
