[PATCH Newlib]Call _fflush_r instead of _fclose_r when cleanup if --enable-lite-exit is in effect

Hi,
Currently there is a FIXME in _cleanup_r in newlib, saying we may want to
call _fflush_r instead of _fclose_r.  This patch fixes the problem by using
--enable-lite-exit.  It makes sense to call light weight function _fflush_r
when lite exit is in effect.

Build and link with/without --enable-lite-exit.  Is it OK?

Thanks,
bin

	* libc/stdio/findfp.c (_cleanup_r): Call _fflush_r when
configuration
	option "--enable-lite-exit" is in effect.  Refactor the code.
