build and ccache

[Erik Joelsson]

Hello,

I have not used ccache in a while. I just tried building jdk9-dev latest 
with ccache and then updating to jdk-9+114 and then running a clean 
build. It worked fine. Which version of gcc and ccache are you using? I 
use the versions from the official devkit.

ccache 3.2.1
gcc 4.9.2
