My first suggestion is that you try building gnu binutils with i686-linux-gnu as a target, and installing it alongside your existing binutils, but with a different --prefix. I don't know if that will really work, but it *seems* like it should. See http://www.gnu.org/directory/binutils.html and follow the links for the mailing list, and the install directions, which you should read with extra care.
