bug#17971: 24.3.92; Patch to fix el compression on RHEL/CentOS 7

[Stephen Hassard]

Here's the relevant output from the 'make install' on CentOS 7:

----
[ -z "/usr/bin/gzip" ] || { \
  echo "Compressing *.el ..." && \
  cd "/home/shassard/opt/emacs/share/emacs/24.3.92/lisp" && \
  find . -name '*.elc' -exec /bin/sh -c \
    '/usr/bin/gzip -9n `expr "$1" : "\\(.*\\)c"`' dummy '{}' ';'; \
}

make immediately fails after this point.

I've attached a revised patch that adds the -9n flag to the gzip command and switch back to -exec for find.

Please tell us how it fails.

Sadly I don't think -execdir is portable.
