One can build for any arch from any other arch (more or less, if not
it's a bug).  amd64 is the name for the 64-bit cpu first produced by
AMD, and which Intel later implemented with feature "EM64T".

There is also a 64-bit cpu called "IA64" which is uncommon and
different.  That is perhasp what "Intel 64-bit architecture" means,
which is different from "Intel's implementation of AMD's 64-bit
