Remove --with-extra-libs option

Remove the --with-extra-libs configure option, which is a functional
duplicate of the --with-wrapper-libs configure option.
--with-extra-libs has not been included in an official release (it has
been in release candidates), while --with-wrapper-libs has existed for
over a decade.
