Don't use arm-linux-gcc, it won't work. There are arm-elf-gcc tools on 
http://ecos.sourceware.org/ if you follow the downloading/installation 
instructions you'll find them.

However the public eCos doesn't have a PXA255 port. Intel wrote their own 
and have never contributed it (and from what I saw of the sources, they 
hacked around a lot of generic source so I'm not terribly surprised). So 
you should use the RedBoot sources from Intel.
