What's the purpose of the `--enable-ld` option of `configure`?

The top-level configure script is shared between GCC and the GNU
binutils and gdb.  The --enable-ld option is relevant for the
binutils, not for GCC.

As far as I know it is not documented other than the --help output.
It is paired with --enable-gold.
