Author: Manolis Ragkousis <address@hidden>

    gnu: cross-base: Build the correct cross-mig.
    
    * gnu/packages/cross-base.scm (xmig): Pass '--target=' instead of
      '--host=' and set the CROSS_CPATH.
    * gnu/packages/hurd.scm (hurd-minimal): Move #:configure-flags
      from here...
      (hurd-headers): ...to here. Change '--build' to '--host'.
