Subject: [bug#59322] [PATCH v2 3/4] gnu: racket-vm-cs: Avoid duplicate work.

From: Philip McGrath <[email-masked]>
Date: Thu, 17 Nov 2022 19:45:32 -0500

Only configure with '--enable-racket' for cross-compilation: otherwise,
it effectively overrides '--enable-scheme' and bootstraps Chez Scheme
again. This change saves a couple minutes of build time. See upstream
discussion at <https://github.com/racket/racket/issues/4492>.

* gnu/packages/racket.scm (racket-vm-cs)[native-inputs]: Only supply a
Racket VM when cross-compiling.
