* guix/scripts/build.scm (%standard-build-options): Change option handlers to support multiple seeds. * guix/scripts/package.scm (show-help): Remove --dry-run, --fallback, --no-substitutes, and --max-silent-time. (%options): Likewise, and add %STANDARD-BUILD-OPTIONS. (%default-options): Add 'verbosity'. (guix-package): Call 'set-build-options-from-command-line' instead of 'set-build-options'.
