I cross compiled guix from x86_64-linux to powerpc-linux and then copied
it over to my powerpc machine.  I can use it to instantiate builds but I
can't copy derivations across the network to my x86_64 box.

My first thought is an issue in our libssh, since we already have
problems cross-compiling that to 32-bit architectures.  The EOF in the
integer sounds like it could be an endian issue, but I'm not sure why
that wouldn't have come up previously.
