    gnu: libpaper: Fix aarch64 cross-compilation.
    
    The packaged config.sub and config.guess do not have aarch64 support. 
Replace
    them by the ones from automake.
    
    * gnu/packages/ghostscript.scm (libpaper)[arguments]: Replace outdated 
config.sub and
    config.guess, taken from ...
    [native-inputs]: ... here, by adding automake.
