[PATCH 8/8] SPU pass errno to perror assist call

[Patrick Mansfield <patmans at us dot ibm dot com>]

The assist call interface changed to take errno as the second argument to
perror, so perror on PPU can use the SPU errno, and not the PPU one.

2007-06-18 Patrick Mansfield <patmans@us.ibm.com>

	* libc/machine/spu/perror.c: Pass errno as the second argument to
	the assist call.
