    For an AT91SAM9263EK board.
    I am adding  AT91 evaluation kits support to u-boot 1.2.0 and I did 
some tests which several EABI compiler  :  codesourcery ,  open embedded 
and buildroot.
    It seems when there is a 64 bits division the compiler refers to 
"_udivdi3" which is not implemented into "u-boot/lib_arm/"  library and 
then try to link with libgcc from compiler  :
