Why is JG64 the correct file?  I used AMD64 last time IIRC.  Both just

Use 'AMD64' kernel config file if it works for you.
Also this is not a crossbuild - why do I need all the above arguments?
It is an AMD64 SMP machine.
I did a buildworld without arguments - do I need to redo it?

If you are building on amd64 you don't need to specify the cross-build 
arguments.
