Ok, so now I'm going to assume you're trying to do this on a 32-bit
FreeBSD/i386 5.3 system; since there aren't any other details otherwise.
First question is why don't you just don't download and install
FreeBSD/amd64 5.3 onto your Athlon64 system?

However, if you want to build an amd64 kernel on an i386 system (ie, a
cross build):

    # cd /usr/src
    # rm -rf /usr/obj/*
    # make cleandir ; make cleandir
    # make TARGET_ARCH=amd64 buildworld
    # make KERNCONF=GENERIC TARGET_ARCH=amd64 buildkernel

note that the 2nd and 3rd steps aren't typically needed, but I have no
idea the state of your /usr/src and /usr/obj dirs.

You're still using the i386 32-bit kernel to build an AMD64 kernel.  The
32-bit i386 compiler doesn't understand the AMD64-specific compiler
switches.
