If your JDK_HOME points to a 64-bit JDK then you will get a 64-bit FX 
build. No additional options are needed. You need to do a "gradle clean" 
as part of your build if you previously built a 32-build in the same 
repo. Also, if not building webkit or media, make sure you update your 
stub_runtime to point to 64-bit FX binaries (your "caches" dir if doing 
a closed build).
