Thanks. If I am trying to build a cross GCC 3.4 (sparc-coff). Do I need to firstly build a sparc-coff GNU binutils before that? Since gcc3.4.6 is a rather old release, which release of GNU binutils would do such a job?

Please reply to the mailing list, not just to me. As far as I know gcc 3.4.6 should support sparc-coff. However, it's hard to provide any useful information about such an old release.
