--- Comment #6 from nsz at gcc dot gnu.org ---
affects all x86 targets (except *gnu unless gcc was configured with
--disable-gnu-indirect-function )

libatomic needs a portable mechanism to dispatch between incompatible
implementations when those can be inlined (or static linked).

(currently there is no diagnostic when incompatible use of atomics are linked
together which can cause dangerous runtime breakage.)
