OK...

So, how the heck did testhello pass?
How are you building the hello world program?

Even if I were to copy these to the local directory I'm sure I would have problems finding the crtBegin.o and gcc libs since these come from a different directory. Before trying to build the kernel I setup the environment variables as:

Yikes.  I think never do any of that crap.  Instead, I just set
CROSS_COMPILE to an absolute prefix, e.g.
CROSS_COMPILE=/opt/crosstool/gcc-3.4.4-glibc-2.3.5/arm-xscale-linux-gnu/bin/arm-xscale-linux-gnu-

Lord, no.  You're making things too hard, I think...
