Thumb as a configuration option is dead (it was originally there to 
support the separate gcc compiler, but the two have long-since been 
merged, so I see no need to keep it).

How about

	arm*b|xscale*b|strongarm*b)	cpu_type=arm endian=big ;;
	arm*|xscale*|strongarm*)	cpu_type=arm endian=little ;;

After all, both xscale and strongarm can be used in a big-endian manner.
