No.  xscale supports both big and little endian.  As an example, on
this board you can switch between big and little endian with a jumper:

The debian ARM port is little endian, and most ARMs are run in little
endian mode, but the Intel IXP* network processors are mostly (always?)
run in big endian mode.
