Log Message:
* Set GNU_CONFIGURE_INFODIR to specify a special location for the info
  files.  Passing --infodir directly doesn't work since only the final
  --infodir is honored by configure scripts, and bsd.pkg.mk adds the
  last one based on the setting for GNU_CONFIGURE_INFODIR.  Drop the
  obsolete use of INFO_DIR.

* List the info files directly in the PLIST.

* Fix the build and the PLIST when using xemacs.

Bump the PKGREVISION to 2.
