How to build 64-bit FX ?

[Anthony Petrov]

Hello,

I'm on Win7 64 bit system. Regularly I use 32-bit compilers and a 32-bit 
JDK, and when building FX by executing the `gradle` command, I get a 
32-bit FX build.

How do I get a 64-bit FX build on the same system? What additional 
software do I need? I suppose I need a 64-bit JDK, right?

I have VS2010 Professional installed. Do I need to install any 
additional development tools/compilers?

What options/environment variables do I specify on the command line to 
run gradle and get a 64-bit FX build?
