The ARM 2005 Q3-2 uses binutils head for the build. We don't currently
support big-endian mode with our toolchain and --be8 is untested.

I reproduced the problem with the following testcase:

echo "EOF" >> test.c
int _start (void)
{
  return 0;
}
EOF
arm-none-linux-gnueabi-gcc -mbig-endian -c test.c
arm-none-linux-gnueabi-ld -EB --be8 -o test test.o
Segmentation fault.

Even if you fix this there is no guarantee that the resulting linux
kernel is going to be runnable. This code will require more support.

Cheers,
Carlos.
