jdk8 build times

[Erik Joelsson]

Nice to see improvement, but it's still far from where it should be. For 
comparison, here are my build times on a similar, but probably slower, 
laptop. Lenovo T410, i5 M 520 2.40GHz and 4GB ram, no ssd. This laptop 
has no anti virus scanning installed.

----- Build times -------
Start 2013-08-28 12:25:00

00:14:07 jdk
00:01:10 langtools
00:00:25 nashorn
00:29:56 TOTAL
