    packages: Apply target triplet in bag-transitive-host-inputs.
    
    Fixes a bug where propagated inputs that should be cross-compiled are 
instead
    compiled for the host system.
    
    * guix/packages.scm (bag-transitive-host-inputs): Call transitive-inputs in
      the context of the bag's target system triplet.
