* sysdeps/unix/mips/pipe.S: Reorder instructions since .reorder is
	default.

	* sysdeps/mips/__longjmp.c (__longjmp): Use $25 to fix problems
	with some applications.
	Patches by Ralf Baechle <ralf@uni-koblenz.de>.

	* sysdeps/mips/bsd-setjmp.S: Use __PIC__.
	* sysdeps/mips/bsd-_setjmp.S: Likewise.
