Looks like you installed from the wrong tarball...
There's this[1] you can use to change your CHOST but I don't think it'll work 
to go from 32 to 64 bits.
You may need to (at your own risk) build a 64-bit kernel (on another machine 
or with a cross compiler), reboot to it, unpack a 64 tarball except config 
files, update CHOST on make.conf, and rebuild everything. And you will likely 
run into problems along the way.
