Did take a second look at the configure.ac file, I think the wanted (and
straight forward) solution is to to relay on the __sync_ built-ins (as
before Thomas Petazzoni patch 'pulseaudio: remove BR2_ARCH_HAS_ATOMICS dependency'
(see [1]), to avoid the special atomic-arm-linux-helpers/atomic-arm-memory-barrier
handling and/or the handling in the else case of the __sync_ test....

The solution would be a partly revert of Thomas commit with a change to BR2_TOOLCHAIN_HAS_SYNC_4
(or similar, not sure how to check which are needed)...

Regards,
Peter
