If anyone would like a reproduction sequence for this, the toolchain I use
(which compiles commit 9933fc0ac1ac14b^1 just fine) is at:

  http://landley.net/aboriginal/downloads/binaries/cross-compiler-sparc.tar.bz2

I configure using the attached miniconfig, ala:

  make allnoconfig KCONFIG_ALLCONFIG=miniconfig.sparc ARCH=sparc

And then:

  PATH=/path/to/cross-compiler-sparc/bin:$PATH make ARCH=sparc \
    CROSS_COMPILE=sparc- -j 3

I then grab the file arch/sparc/boot/image out of the build and run:

  qemu-system-sparc -nographic -no-reboot -kernel image -hda /dev/null -m 256 \
    -append "root=/dev/sda rw init=/sbin/init.sh panic=1 PATH=/bin:/sbin console=ttyS0 HOST=sparc"

If you'd like a working system for comparison (built with the same
toolchain), download:

  http://landley.net/aboriginal/downloads/binaries/system-image-sparc.tar.bz2

And run-emulator.sh out of that.
