newlib: clean up autoheader templates

Sync these back from newlib.hin to configure.ac, and touchup some of
the forms to be consistent (like being full sentences).  Also use the
AC_DEFINE-vs-AC_DEFINE_UNQUOTED macros correctly.  This will make it
easier to re-enable autoheader for managing newlib.hin.
