Honestly, I don't *THINK* it will be necessary to use a cross-compiler
to build a 64-bit kernel, but then again, I've never personally built
a kernel on a system that wasn't already 64-bit capable - perhaps Ryan
or Matt could speak up more on this. But, the kernel compilation is
pretty well self-contained, not requiring anything else to complete
properly, and therefore it may very well be possible to use a 32-bit
GCC. But, you could of course use your shiny new Cross-GCC to build
the kernel using make ARCH=x86_64 menuconfig and so on.
