[arm] Fix bootstrap - missing initializer in tail entry of autogenerated code

My patch yesterday accidentally missed a hunk that added the
update to the tail entry of the autogenerated data structure
produced by parsecpu.awk.  This causes native bootstraps to
fail.

This patch adds back the missing hunk.

	* config/arm/parsecpu.awk (gen_comm_data): Add initializer for
	profile to the dummy entry at the end of the list of architectures.
	* config/arm/arm-cpu-cdata.h: Regenerated.
