OpenJDK 7 64-bit Mac

I updated the Darwin10Build instructions for building the BSD port of OpenJDK 7 on the OpenJDK wiki at Oracle. I successfully built 32-bit binaries, but decided to see if I could get it to build 64-bit binaries by changing the ARCH_DATA_MODEL=64 parameter to the build script. It worked. It reports that the build is amd64, but it is running on a MacBook Pro Intel Core Duo system. I added my 64-bit build script to the Darwin10Build instructions. Here is an image of my 64-bit build running tomcat. You can see the build is listed 1.7.0-internal-jyeary, and the OS Architecture amd64.
