  No. I think problems are in linker script.

  I use sdelinux-5.03.06-1 (gcc-2.96) and gcc-3.3.4 from uClibc toolchain.
  both compiler needs to apply attached changes.

  Maybe your compiler can generate a file for little-endian code to big-endian
  binary format. but sdelinux or uClibc toolchain are not.

  Please report If your compiler does not have problems with this patch, 
  if it is noproblem, consider to marge this. > support at denx.de

What I change is:
 remove OUTPUT_FORMAT: It will use default format.
 remove -EL or -EB : It will use toolchain default.
