Subject: ELF unexec: Correct section header index

Emacs should build on ppc64el.  A problem with the bss has been fixed.

This upstream patch has been added [1/10]:

ELF unexec: Correct section header index

First a small fix.  The code incorrectly uses "NEW_SECTION_H (n)" when
  it should have been using "NEW_SECTION_H (nn)" to find the name of the
  section currently being processed.  Of course, before the bss
  sections, n and nn have the same value, so this doesn't matter except
  in the case of .sbss.  For .sbss this probably meant .bss (most likely
  the next section) was copied from memory.  A later patch removes the
  bogus .sbss handling anyway.

* unexelf.c (unexec): Use correct index to look up names.
