You cannot bootstrap the 64-bit compiler with a 32-bit compiler.
The GCC build framework doesn't currently distinguish between build
libraries and host libraries, so effectively it requires (build == host)
for a bootstrap.

If you omit --with-cpu=ultrasparc the bootstrap will be
straightforward, resulting in a compiler that can run on a 32-bit host but
still generate executables for 64-bit ultrasparc.

Bootstrapping in two steps as you say is one workaround, building a cross
compiler is another.
