The QUEUED_LOCK_STAT option to report queued spinlocks statistics was
previously allowed only on x86 architecture. Now queued spinlocks are
used in multiple architectures, we now allow QUEUED_LOCK_STAT to be
enabled for all those architectures that use queued spinlocks. This
option is listed as part of the general architecture-dependent options.
