OSAtomicCompareAndSwapPtrBarrier, used in a macro definition in hb_atomic_private.hh, didn't appear until 10.5.

That can be worked around by including <AvailabilityMacros.h> and adding OS_X_VERSION_MAX_ALLOWED > OS_X_VERSION_10_4 to the condition, which will force it to use the HB_NO_MT version.

The next problem, which I haven't worked around yet (time to go make dinner) is in hb-ot-layout-common-private.hh, where g++ complains that OT::CoverageFormat1::Iter and OT::CoverageFormat2::Iter are private in the context of the union at line 645.
