Description Florian Weimer 2018-09-21 11:44:03 UTC 
+++ This bug was initially created as a clone of Bug #1631728 +++

We need to backport this commit for 32-bit CET support:

commit 2339d6a55eb7a7e040ae888e906adc49eeb59eab
Author: H.J. Lu <hjl.tools>
Date:   Wed Sep 12 08:40:59 2018 -0700

    i386: Use ENTRY and END in start.S [BZ #23606]

This affects the statically-linked startup code, so binaries will have to be rebuilt.
