Log message:
	gas: mips: fix segfault with invalid default cpu strings
	
	If you configure gas for a mips32el-* target, the default cpu calculation
	gets mangled, and we end up passing and invalid value as the default cpu.
	
	If you try executing gas after that, it segfaults.  This is because it
	assumes that the default cpu value is always valid.
	$ ./gas/as-new
	Assembler messages:
	Error: Bad value (2) for default CPU
	Segmentation fault (core dumped)
	
	I'm not debating that the target tuple is valid, just that gas shouldn't
	crash.  So add a friendly assert to avoid that.
