problem in cross compiling newlib

Newlib as a *module* only knows about $host, but the *toplevel*
configury, which manages all the modules (libgloss, gcc, gas, gdb,
libiberty, etc) follows the standard where --target is the target,
--host is where you run the tools, and --build is the machine running
configure.

It will rearrange the options when it sub-configures into newlib.

Of course, you could have just tried both and watched what happened.
