is this enough to determine what I have done wrong

Toady I managed to get Aurora installed on my U2
after wasting a day realizing that /boot needed to be
ext2 =-}
   Now that it is up and running I thought I would try
and rebuild the Kernel.  I downloaded 2.4.20
and patched it to
patch-2.4.21-rc2

everything went fine until it tried to link (I think)
Below is a clip, I hope it is enough that someone
can tell me my fatal error.
Thanks
Brian
