704f794714 powerpc: Fix missing barriers in atomic_exchange_and_add_{acq,rel} 
On powerpc, atomic_exchange_and_add is implemented without any
barriers.  This patchs adds the missing instruction and memory barrier
for acquire and release semanthics.

1ea339b697 Add arch-specific configuration for C11 atomics support. 
This sets __HAVE_64B_ATOMICS if provided.  It also sets
USE_ATOMIC_COMPILER_BUILTINS to true if the existing atomic ops use the
__atomic* builtins (aarch64, mips partially) or if this has been
tested (x86_64); otherwise, this is set to false so that C11 atomics will
be based on the existing atomic operations.
