undefined symbol '__divdi3' & '__moddi3' on linux kernel 2.6.10 (toolchain Linuxi386/Mips32)

["David Sanchez" <david.sanchez@lexbox.fr>]

Hi,

I'm a newby on Linux/Mips more my English is very poor so sorry...
But I have a big problem (for me):

I want to cross-compile my linux kernel 2.6.10 on my PC i386 for mips32
(alchemy AU1550) CPU.
I developed a module that contains some operations on types loff_t (i.e
long long) such as div and mod. The code is in a foo.c file.

I successfully built a cross toolchain using:
The bin utils (Bintuils-2.15), the glibc headers (glibc-2.3.5) and the
gcc core (gcc-3.4.4).

The compilation of the kernel works but unfortunately the link generates
two error messages on the file foo.c:
Undefined reference to '__divdi3'
Undefined reference to '__moddi3'

What I'm doing wrong ? 
Why the gcc doesn't embed the symbol implementation ? 
And so where can I found an implementation ? 

Thanks for all your help
