Confirming JDK 8 GA version

The source/makefiles are not aware of the build number. It's assigned 
from an external source at the time of building a promoted build. If you 
want your version number to better match 8 GA, you will have to play 
around with the configure arguments --with-build-number and possibly 

Also, as David pointed out, in JDK 8, hotspot has it's own numbering.
