Maybe you could try just using the 2.0.1 sources from here:

You could try passing the verbose flags and see what
headers and libs get used during the build.  Maybe
you'll find some problem there.  I think those would
be something like:

  gcc -v -Wl,--verbose ...

Or maybe just use:

  ld --verbose ...

BTW, have you looked at the petitboot bootloader? For
the most part it is a better choice than kboot.
It provides essentially all the functionality that
kboot does, plus more, it is easier to build, and it
is a currently maintained project.

The petitboot package can be built for x86.  That is
how much of its development is done, but OpenWRT does
not yet support an x86 build of petitboot (that
would create a grub second stage image).  My plan is
to add x86 PC support next.  I don't think it is very
difficult to do, I just have not had time to do it.

You can see some screen shots of petitboot built for
the PS3 here:

  http://www.kernel.org/pub/linux/kernel/people/geoff/cell/ps3-petitboot/

My petitboot development repo is here:

  http://git.kernel.org/?p=linux/kernel/git/geoff/petitboot-dev.git
