This question make no sense.  Of course you can debug a kernel on an
Intel system using an AMD system.  There isn't anything CPU vendor
specific within a single architecture that would affect you doing this.

But I don't think that's really your question.  I think you're asking if
you can debug a FreeBSD/i386 kernel using a FreeBSD/amd64 system.  I.e.
cross-platform debugging.

The answer is "no" using stock FreeBSD bits.
A single GDB binary cannot be built multi-platform.
