Remove the do_configure_prepend which is used for removing ${S}/m4/lib-link.m4 to compile under libtool 2.2.2, but our libtool has been upgraded to 2.4.2, and: for the 3 recipes: gst-plugins-bad_0.10.22.bb gst-plugins-base_0.10.35.bb gst-plugins-good_0.10.30.bb They don't have m4/lib-link.m4 any more. For the gst-plugins-ugly_0.10.18.bb, though it has m4/lib-link.m4, our libtool version is now 2.4.2, so we can remove the do_configure_prepend from all of them.
Drop this since it's invalid, the m4/lib-link.m4 still exists in two pkgs.
