It is better to use "-f batch+native-compile", I think.

  emacs -batch --eval "(message \"%s\" system-configuration-features)" | grep NATIVE_COMP

${prefix}/share is for architecture-independent files, so it's the
wrong place.

More importantly: why do you want to install them somewhere? why not
let Emacs compile them when they are first used and store them in
~/.emacs.d/eln-cache?  I think that's the canonical way at the moment.
