I think the problem is that you disabled tests in your 'guix-x86_64'
package, which makes it a different derivation than the one built by
Hydra.  In order for this approach to work, you must ensure that you
only use substitutes until you can run a guix-daemon (and guix?) for
x86_64.  guix-daemon for i686 can download substitutes for x86_64, but
cannot build anything for x86_64.
