changing version infomation string of 'java -version'

[Erik Joelsson]

Hello Matthias,

The update version (the 31 in this case) you can set using the configure 
parameter --with-update-version=31. In JDK8u, the source does not know 
the correct value for this version number, so the distributor who builds 
it needs to know and set it correctly.
