* target.h (target_waitstatus_to_string): Declare.

Browse Source 
* target.c (target_waitstatus_to_string): New function.  Copied from
	debug_to_wait.  Add missing entries for TARGET_WAITKIND_SYSCALL_ENTRY,
	TARGET_WAITKIND_SYSCALL_RETURN, TARGET_WAITKIND_IGNORE,
	TARGET_WAITKIND_NO_HISTORY.
	(debug_to_wait): Call it.
	* infrun.c (wait_for_inferior): If debug_infrun, print result of
	target_wait.
	(fetch_inferior_event): Ditto.
