    gnu: emacs: Check integrity of native-compiled files.
    
    In the previous commit, we've added a patch that potentially messes with
    how built-in (especially preloaded) Lisp libraries are loaded.  Thus, we
    might want to assert that these files still load fine, as reported when
    querying the builtin documentation of functions provided by them.
    
    * gnu/packages/aux-files/emacs/comp-integrity.el: New file.
    * gnu/Makefile.am (dist_noinst_DATA): Register it here.
    * gnu/packages/emacs.scm (emacs-no-x)[#:phases]: Add 
‘validate-comp-integrity’.
