commit baf38965aaddd5cf6c3ce40902c2321d74463e67
Author: Caleb Ristvedt <caleb.ristv...@cune.org>
Date:   Fri Apr 19 12:48:55 2019 -0500

    config: add variables for more directories, %impersonate-linux-2.6?
    
    * guix/config.scm.in: renamed to guix/config.scm.in.in
    
    * guix/config.scm.in.in (%temp-directory, %libexecdir, 
%impersonate-linux-2.6?):
      new variables.
    
    * configure.ac: Add options impersonate-linux-2.6-default and tmpdir and
      substitute them. Adjust from config.scm.in to config.scm.in.in.
    
    * Makefile.am: Substitute libexecdir in guix/config.scm.in to produce final
      result, guix/config.scm.
    
    * guix/store/build-derivations.scm (%temp-directory): removed, no longer
      needed.
