4df4275506
Tested with/without guile,python on amd64-linux. I'm not sure we still have to deal with shells that can't handle empty for lists, but I played it safe. Otherwise this patch would be a lot smaller (though a diff -b will still show the real changes). PR build/17105 * configure.ac: Add AM_CONDITIONALs for HAVE_PYTHON, HAVE_GUILE. * configure: Regenerate. * data-directory/Makefile.in (PYTHON_FILE_LIST): Renamed from PYTHON_FILES. (PYTHON_FILES): New variable. (GUILE_FILE_LIST): Renamed from GUILE_FILES. (GUILE_FILES): New variable. (stamp-python, install-python, uninstall-python): Handle empty file list. (stamp-guile, install-guile, uninstall-guile): Ditto.
