Naturally, it looks like I may have spoken too soon.  After booting
Linux to verify the hardware was working, RTEMS seems to be much
happier.  I was also experimenting with linking in some static data
for the untar from memory stuff, which might have been messing things
up.  Anyhow, its booting more happily now.

I'm using the normal RTEMS compiler & binutils suite as offered on the
OAR ftp server.
So, for now its working, and I apologize for the false alarm.
