OK, since I have a mostly-working nfsroot and a cross-built toolchain I tried 
running gcc. I just tried "gcc -o hello hellow.c" where hellow.c is the hello 
world program from cvs->userspace. The compiler dies with signal 6(abort). The 
system is also pretty erratic, sometimes the prompt takes a few minutes to 
return.(once with an out-of-memory error)

Someone suggested that I try an older kernel from before the stack changes 
were made eariler this month, so I tried an old kernel I had around(built with 
an old xc). Now gcc gets a little further, but dies with,

I also wanted to try the older kernel bits built with the new xc but I 
couldn't remember the -ffunction-section magic to make it work.

If other people want to play with this I have put my new nfsroots at,
