It got added by Ulf back in 2007, but there's no references to it anywhere,
so remove it.

-Run `autoconf' (and `autoheader', `aclocal', `automake', `autopoint'
-(formerly `gettextize'), and `libtoolize' where appropriate)
-repeatedly to remake the GNU Build System files in specified
-DIRECTORIES and their subdirectories (defaulting to `.').
-
-By default, it only remakes those files that are older than their
-sources.  If you install new versions of the GNU Build System,
-you can make `autoreconf' remake all of the files by giving it the
-`--force' option.
-
-Operation modes:
-  -h, --help               print this help, then exit
-  -V, --version            print version number, then exit
-  -v, --verbose            verbosely report processing
-  -d, --debug              don't remove temporary files
-  -f, --force              consider all files obsolete
-  -i, --install            copy missing auxiliary files
-      --no-recursive       don't rebuild sub-packages
-  -s, --symlink            with -i, install symbolic links instead of copies
-  -m, --make               when applicable, re-run ./configure && make

-The environment variable \`WARNINGS\' is honored.  Some subtools might
-support other warning types, using \`all' is encouraged.
-
-Library directories:
