self: Use default config variable values for derivations.
The value of %localstatedir, %storedir, and %sysconfdir is known to have no impact on the compilation of the Guix modules. Thus, explicitly build those modules against a (guix config) module that uses all the default values. That way, a Guix installation that uses different config values can still benefit from substitutes. Reported by Ricardo Wurmus. * guix/self.scm (%default-config-variables): New variable. (make-config.scm): Add #:config-variables and honor it. (compiled-guix)[*core-modules*]: Pass #:config-variables to 'make-config.scm'.
