bug#19672: 25.0.50; make bootstrap fails on git HEAD

[Paul Eggert <eggert@cs.ucla.edu>]

Thanks for reporting that.  I see the same failure as you on my platform (Fedora 
21 x86-64), but I get another failure earlier, as follows:

   ELC      gnus/nnregistry.elc
Warning: Using brain-dead macro `mm-with-unibyte-current-buffer'!
utf7.el: `mm-with-unibyte-current-buffer' is an obsolete macro (as of 25.1).
../emacs-lisp/eieio.el: `eieio-object-name-string' is an obsolete generic 
function (as of 25.1); use `eieio-named' instead.
../emacs-lisp/eieio-base.el: `eieio-object-name-string' is an obsolete generic 
function (as of 25.1); use `eieio-named' instead.

In toplevel form:

A bisect finds that the nnregistry bug was introduced by this recent commit, and 
I suspect that this change is causing your problem too:

     * lisp/emacs-lisp/cl-generic.el (cl-no-primary-method): New fun and error.
     (cl--generic-build-combined-method): Use it.

I'll CC: this email to Stefan to give him a heads-up.
