The binutils you are using was built in big-endian mode (since you are
using a target triple of the form arm*b-*-*, it automatically switches
to using big-endian by default), but gcc doesn't have the "default to
big-endian if the target machine is arm*b" logic merged upstream.

So, you will need a patch for gcc to default to big-endian based on
the target triple.  crosstool has a couple of patches like that for
gcc 3.3, 3.4 and I believe 4.0 -- try forward-porting one of them.
