pull: Build with the matching Guile major version.
Previously, 'guix pull' would always build with Guile 2.0. Now it builds with the Guile that matches (effective-version). * build-aux/build-self.scm (false-if-wrong-guile) (package-for-current-guile): New procedures. (guile-json, guile-ssh): Use it. (guile-for-build): New procedure. (build): Use (effective-version) instead of the hard-coded "/2.0". Add (guix modules) closure to #:modules argument. Pass \#:guile-for-build argument to 'gexp->derivation'. * guix/build/pull.scm (depends-on-guile-ssh?, all-scheme-files): New procedures. (build-guix): Show the output of (version). Use the above procedures. Filter out files that match 'depends-on-guile-ssh?' when (ssh session) is missing.
