This fixes x86_64-native-linuxapp-clang build with
CONFIG_RTE_FORCE_INTRINSICS=y:
include/generic/rte_atomic.h:218:9: error:
implicit declaration of function '__atomic_exchange_2'
is invalid in C99 [-Werror,-Wimplicit-function-declaration]
include/generic/rte_atomic.h:501:9: error:
implicit declaration of function '__atomic_exchange_4'
is invalid in C99 [-Werror,-Wimplicit-function-declaration]
include/generic/rte_atomic.h:783:9: error:
implicit declaration of function '__atomic_exchange_8'
is invalid in C99 [-Werror,-Wimplicit-function-declaration]
We didn't caught this issue previously on other platforms because
CONFIG_RTE_FORCE_INTRINSICS enabled by default only for armv8.
