    gnu: chez-scheme-for-racket-bootstrap-bootfiles: change for aarch64.
    
    * gnu/packages/chez.scm (chez-scheme-for-racket-bootstrap-bootfiles):
    change for build on aarch64, making racket available on aarch64.
    [arguments] use --machine even when architecture is supported by Racket's
    fork of ChezScheme.
