* linux-low.c (linux_remove_process): Add `detaching' parameter. 

Pass it to thread_db_free.
	(linux_kill, linux_detach, linux_wait_1): Adjust to pass the
	proper `detaching' argument to linux_remove_process.
	* linux-low.h (thread_db_free): Add `detaching' parameter.
	* thread-db.c (thread_db_init): Pass false as `detaching' argument
	to thread_db_free.
	(thread_db_free): Add `detaching' parameter.  Only
	call td_ta_clear_event if detaching from process.
