    Description

      SERVER-51722 added -moutline-atomics on AArch64 in order to dynamically use LSE atomics on architectures that supported it. Since then we realized WT needs LSE atomics for correctness ( WT-9256 ) and we bumped the minimum target to armv8.2-a both for master ( SERVER-55178 ) and older branches ( SERVER-71772 ) in order to guarantee LSE atomics support. This means we no longer need the -moutline-atomics flag.
