On Cell CPUs (blades and PS3) we should mount the spufs virtual file system on /spu.
The fact that we're running on Cell can be determined by the existence of 'Cell'
in /proc/cpuinfo, or the existence of /proc/device-tree/cpus/CBE*
Alternatively perhaps by trying to load the spufs.ko module and then looking for
'spufs' in /proc/filesystems.
Just commited some changes to handle this.
mount: mount point /spu does not exist
Bah missed that - added an update to yuminstall.py to create /spu on cell.
