Those are coming from the system linker. Which probably means you are using the system assembler, too. Or maybe even the odd case where you're using binutils for the assembler but the system linker. Can you try with using binutils for the assembler and linker? I am assuming you either have an older version of GCC for building the newer version of it, or perhaps you have the Sun Pro compilers. In any case, you could use whichever bootstrap compiler you have to build binutils, and then put they binutils in PATH. The GCC configure script should then chose those for building.
