utils: Add `guile-version>?', and use it.
This fixes Guile version comparisons when (version) has a vendor-specific suffix. Reported by Andreas Enge <andreas@enge.fr>. * guix/utils.scm (guile-version>?): New procedure. * tests/utils.scm ("guile-version>? 1.8", "guile-version>? 10.5"): New tests. * guix/scripts/substitute-binary.scm (fetch, progress-report-port): Use `guile-version>?' instead of `version>?'. * guix/http-client.scm (when-guile<=2.0.5, http-fetch): Likewise.
