cross compiling ia64!

Hi,
I have been trying ,rather unsuccessfully, to cross compile the linux
kernel 2.6-test3 using the compiler inside the NUE 1.2.

I get the following errors using gcc version 2.96-ia64-000717 snap
001117)

arch/ia64/scripts/check-gas-asm.S: Assembler messages:
arch/ia64/scripts/check-gas-asm.S:1: Error: Expected ':'
arch/ia64/scripts/check-gas-asm.S:1: Error: Rest of line ignored. First
ignored character is `:'.
arch/ia64/scripts/check-gas-asm.S:2: Error: backw. ref to unknown label
"1:", 0 assumed.
ia64-hp-linux-objdump: /tmp/out17472.o: No such file or directory
arch/ia64/scripts/check-gas: [: !=: unary operator expected
arch/ia64/Makefile:41: *** Sorry, your compiler is too old.  GCC v2.96
is known to generate bad code..  Stop

so I tried the following:
Replaced the gcc with 3.0.1 & binutils with 2.11. The binutils still
gave problems, replaced them with 2.14. This took care of the assembler
problem and gcc warning, but the kernel compile fails at
arch/ia64/kernel/signal.c

My guess that 3.0.1 may not be the correct version for compiling 2.6. I
have also tried to compile 2.95.3 (as suggested in the README) for ia64,
but it seem that 2.95.3 does not support ia64 configuration. Any
pointers/references to solve this?

thanks

the complete build output is as below:

warning: your linker cannot handle cross-segment segment-relative
relocations.
         please upgrade to a newer version (it is safe to use this
linker, but
         the kernel will be bigger than strictly necessary).
