RFR: 8187227: Zero should use compiler built-ins for atomics on linux-m68k

[Robbin Ehn]

Hi, a bit out of scope, mostly for Andrew.

Not sure how old compiler you want to be use but __sync_XXX is 'legacy' since 4.7.
So shouldn't we change to __atomic_XXX ?

Manual vaguely says: "They should not be used for new code which should use the ‘__atomic’ builtins instead."
