I plan to add a sparc64 target built from source to Aboriginal Linux.

For a lot of the 64-bit targets, actual 64 bit userspace support is  
strangely lacking. For ppc64 they say to use ppc32, and I've been told  
that about sparc64 as well. I don't know if this is an optimization or  
a requirement. I have a 32 bit image, I'd like to test the 64 bit  
codepaths as well...
