gnu: chez-scheme-for-system: Adjust for bytecode backend. 
Change 'chez-scheme-for-system' to return 'chez-scheme-for-racket' in
two cases when it previously returned 'chez-scheme':

 1. When 'chez-scheme' is not distributed with bootstrap bootfiles,
    since we can only cross-compile 'chez-scheme' for those systems; and

 2. When neither 'chez-scheme' nor 'chez-scheme-for-racket' supports
    native code generation, since we will be able to use the ``portable
    bytecode'' backends of 'chez-scheme-for-racket' as soon as the
    issues in <https://racket.discourse.group/t/950> are resolved.

* gnu/packages/chez.scm (chez-scheme-for-racket): Change condition.

;; Commentary:
;;
;; The bootstrapping paths for Chez Scheme and Racket are closely
;; entwined. Racket CS (the default Racket implementation) is based on (a fork
;; of) Chez Scheme. Racket's variant of Chez Scheme shares sources for
;; nanopass and stex with upstream Chez Scheme.
;;
;; Racket's variant of Chez Scheme can be bootstrapped by an older Racket
;; implementation, Racket BC, which can be bootstrapped from C. Porting that
;; code to work with upstream Chez Scheme (or finding an old version that
;; does) is our best hope for some day bootstrapping upstream Chez Scheme from
;; source.
;;
;; Code:
(define* (chez-scheme-for-system #:optional
(system (or (%current-target-system)
(%current-system))))
"Return 'chez-scheme' if it fully supports SYSTEM, including support for
bootstrapping and native threads. Otherwise, return

;; - `os` is a string for the OS part of a Chez Scheme machine type; and
;; - `arch` is a string for the architecture part of a Chez machine type.
;;
;; The absence of an entry for a given arch--os pair means that neither
;; upstream Chez Scheme nor the Racket variant can generate native code for
;; that system. (The Racket variant can still provide support via its
;; ``portable bytecode'' backends and optional compilation to C.) A value

;;
;; The arch--os pairs marked "commented out" have been commented out in the
;; STeX source for the upstream release notes since the initial release as
;; free software, but they are reported to work and/or have been described
;; as supported by upstream maintainers.
;;
;; For this overall approach to make sense, we assume that Racket's variant
;; of Chez Scheme can generate native code for a superset of the platforms
;; supported upstream, supports threads on all platforms it supports at all
;; (because they are needed for Racket), and doesn't need bootstrap

The Racket package @code{cs-bootstrap} (part of the main Racket Git

7.1 and later, including the Racket BC variant.
Note that the generated bootfiles are specific to Racket's fork of Chez
