The stdout always becomes line buffered mode.

[Kazuhiro Fujieda]

The latest newlib always sets the stdout to the line buffered
mode against the standard quoted below.

  ISO/IEC 9899:1999, Second Edition 1999-12-01, p.266
    As initially opened, the standard error stream is not fully buffered;
    the standard input and standard output streams are fully buffered if
    and only if the stream can be determined not to refer to an interective
    device.

The following patch can correct it.

2001-04-27  Kazuhiro Fujieda  <fujieda@jaist.ac.jp>

	* libc/stdio/findfp.c (__sinit): Don't set stdout to line buffered
	mode here, because it is properly set by __smakebuf in makebuf.c.
