[PATCH 5/8] newlib: move version defines out of the config headers

[Mike Frysinger <vapier@gentoo.org>]

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.
