It's taken a while to work out the answer to this question, but I think I've found it. The old FPGA stuff that was actually released: http://balloonboard.org/files/balloon3/distro/test-v0.3/ is old-arm, rather than eabi. It corresponds to svn r260 I tried going back and rebuilding this, but it doesn't work, and only knows how to build old arm ABI binaries anyway. So I moved on to just before the VLIO changes. : r839 which only requires one patch to build: to build with a vaguely recent version of glibc installed you need to either add the patch below to the initrd quilt series (copy it into initrd/patches and add getline.patch to the end of the series file) or let it build until it barfs, with a 'getline redefined' whinge then apply the patch manually.
