I just noticed that statically compiled OpenBIOS for Unix executable also works!

qemu-sparc64 ./openbios-unix-static
done.

This means that now the CPU emulation should be good enough for
OpenBIOS in system emulator also. I suspect register window trap
handlers or memory management prevent it from working.
