Change 124909 by gonzo at gonzo_wooster on 2007/08/08 17:25:00

	o Default gcc/mips arch to mips32. Default ABI is already set to 32
	    but default CPU type for this ABI is mips1. It causes some
	    inconveniences so far:
		- ll/sc (used for atomic ops) are unsupport by mips1.
		- TARGET_CPU_TYPE should be set explicitly for our primary
		    target platform - mips32.
	Approved by:	cognet, imp
