Isn't that what I just wrote? Liu doesn't need to change
any source code in *newlib* but does need to recompile it with
the proper configuration -- just as he recompiled gcc and binutils.
He is not adding a new target, otherwise he wouldn't be asking
this question (after adding a new target to gcc and binutils),
merely switching from one existing target to a different one.
