First build-infra push to jdk8 -- try out the new build system!

[Weijun Wang]

I'm trying it on my Linux x64 now. The first feeling is that my computer 
is slowed down a lot more than the old build. The 4 CPUs all show a near 
100% usage (it's building hotspot now). The guide says I can adjust it 
with --with-num-cores, but it's only available for configure time and 
not make, right?

Also, the build output directory name is 
build/linux-x64-normal-server-release/, the executables are in 
build/linux-x64-normal-server-release/jdk/bin, and images in 
build/linux-x64-normal-server-release/images/j2sdk-image. All my 
existing scripts need to be modified.

Thanks
Max

We do not yet have full platform support, nor are all parts of the old build converted (but then we fall back on the old build system), and there are likely to be bugs. Most of all, we need to have exposure on a wide range of different build systems, since the reality is always so much messier than you'd want to believe. :-) Please help us to resolve such issues early by trying the new build system!
