Producing community binaries for OpenJDK

Hi Jonathan,

Yep, your links are the type of thing I'm thinking.

As you may have seen from the existing work by AdoptOpenJDK, there are a
few more steps to building a 'usable' OpenJDK (getting the freetype font
code, cacerts, etc), then running a few tests on it, and publishing the
result -- but the overall approach is right.
