[dpdk-dev] [PATCH] eal/x86: fix pedantic build

[Thomas Monjalon]

When enabling pedantic compilation with CONFIG_RTE_LIBRTE_MLX5_DEBUG,
the compiler complains about non standard 128-bit integer type:

include/rte_atomic_64.h:223:3: error:
ISO C does not support ‘__int128’ types [-Werror=pedantic]

It must be marked as an extension of the standard C language
to be accepted in pedantic compilation.
