(define-public %final-inputs-riscv64
+ ;; This is similar to the added (list gcc "lib") elsewhere in this file, but
+ ;; due to how (%current-system) is re-defined when performing builds with the
+ ;; '--system' flag, %final-inputs is too early in the evaulation pipeline to
+ ;; correctly identify the system for which a derivation will be built. Thus,
+ ;; since (%current-system) is re-determined by (guix build-system gnu) after
+ ;; loading %final-inputs but before taking into account the '--system' flag,
+ ;; the test for (target-riscv64?) needs to be in (guix build-system gnu),
+ ;; with %final-inputs-riscv64 already available at the same time that
+ ;; %final-inputs is available.
