bug#57789: Emacs 28.1 clone build with native compilation crashes on s390x

[Rob Browning]

On zelenka.debian.org https://db.debian.org/machines.cgi?host=zelenka
the build crashes with a segfault with current Debian sid (unstable).  I
can produce the crash like this:

  git clone --single-branch --branch emacs-28 .../emacs.git
  cd emacs
  ./autogen.sh
  ./configure --prefix=/home/rlb/opt/emacs-tmp --with-native-compilation
  make check

The debian package produced a similar failure earlier:

  
https://buildd.debian.org/status/fetch.php?pkg=emacs&arch=s390x&ver=1%3A28.1%2B1-3&stamp=1662863442&raw=0

Here's the final bit of the clone build's log, and I'm happy to help
test on the machine if that'd be useful:
