Liu is asking if *newlib* needs to be modified, not if his
*own* code needs adaptation.
I expect newlib source code to be cogniziant of endianess.
However you will need to recompile newlib using the proper configuration
values -- which I don't know, unfortunately. I expect something
like armbe -> armle (be/le big/litte endian).
