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

[Magnus Ihse Bursie]

The build-infra project [1] has been working for a while with creating a 
new build system. The goals of the project include, but are not limited 
to, improved build performance and improved ease of use.

The first part of this project has now been pushed to the jdk8 master 
forest. This means that the new build system is available for you to try 
out! The old build system is still there, and if you want to continue to 
use it, you will notice no difference (for now...).

But if you are interested in trying the new build system, we welcome you 
to experiment with it! The basic operation is:
   cd common/makefiles
   ../autoconf/configure
   make

More information is available in the new build README [2]. If you want 
to try the new build system, please read it first.

Please note that the new build system is not yet complete. 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!

Any questions or discussions on the new build system should be sent to 
build-dev at openjdk.java.net.
