    gnu: commencement: Make ‘glibc-final’ immune to ‘%current-target-system’.
    Previously, the value memoized for ‘glibc-final’ was influenced by that
    of ‘%current-target-system’ since it is used as a default argument to
    ‘libc-for-target’.  Thus, due to the order in which modules were loaded
    versus the time at which ‘%current-target-system’ was set, it was
    possible to end up with ‘glibc-final’ set to the “wrong” libc, for
    instance when doing:
      guix build -f guix.scm --target=i586-pc-gnu
    from another project such as the Shepherd.
    This is similar to the problem fixed in
    * gnu/packages/commencement.scm (glibc-final-with-bootstrap-bash)
    (glibc-final): Explicitly pass (%current-system) as the first argument
    to ‘libc-for-target’ so that the value of ‘%current-target-system’ at
    that time has no influence.
