Here is the content from bugzilla:

Description of problem:

When built with a binutils that activties RELRO by default, emacs now fails to build on ppc64le.  Since RELRO is mandatory, emacs must be updated.

Version-Release number of selected component (if applicable):

Happens with binutils-2.23.52.0.1-35 and newer


Excerpt:
Loading /builddir/build/BUILD/emacs-24.3/lisp/vc/ediff-hook.el (source)...
Loading /builddir/build/BUILD/emacs-24.3/lisp/tooltip.el (source)...
Finding pointers to doc strings...
Finding pointers to doc strings...done
Dumping under the name emacs
emacs: Program segment above .bss in /builddir/build/BUILD/emacs-24.3/build-gtk/src/temacs
make[2]: *** [bootstrap-emacs] Error 1
make[2]: Leaving directory `/builddir/build/BUILD/emacs-24.3/build-gtk/src'

Expected results:

Successful build.

Additional info:

Turning off dump/unexec works around the issue and allows the build to succeed.
