Subject: newlib: move version defines out of the config headers

This will make it easier to move newlib.h to use autoheader directly.
We only want the newlib version defines in our hand curated version
file, _newlib_version.h, not in the template header, newlib.h, so
using AC_DEFINE doesn't make much sense.
