    gnu: commencement: Add support for a native GNU/Hurd system.
    
    * gnu/packages/commencement.scm (kernel-headers-boot0): New procedure.
      (flex-boot0, bison-boot0, gnumach-headers-boot0, mig-boot0,
      hurd-headers-boot0, hurd-minimal-boot0, hurd-kernel-headers-boot0,
      ld-wrapper-boot0): New variables.
      (%boot1-inputs): Add ld-wrapper-boot0.
      (glibc-final-with-bootstrap-bash)[propagated-inputs]: Replace with
      kernel-headers-boot0.
      [inputs]: Add "mig".
      (glibc-final)[arguments]: Replace with kernel-headers-boot0.
