If Emacs is the first or only package that installs its Info files
into an otherwise empty directory (e.g., in Gentoo Emacs is configured
with --infodir=/usr/share/info/emacs-23 to allow for multiple Emacs
versions), then all entries in the resulting dir file will occur
twice.

The bad Info dir file installed by Emacs 23.2 is attached.

The cause appears to be that the Makefile first copies the pre-made
dir file, but then also calls install-info for each Info file.

Attached patch fixes the problem for me. I suggest that this should be
applied to the emacs-23 branch.

	* Makefile.in (install-arch-indep): Don't run install-info if the
	pre-made Info dir file is being installed.
