eal/x86: fix build with gcc 5.3.1

In fedora 22 with GCC version 5.3.1, when compile,
will result an error:

    include/rte_memcpy.h:309:7: error: "RTE_MACHINE_CPUFLAG_AVX2"
                                is not defined [-Werror=undef]
    #elif RTE_MACHINE_CPUFLAG_AVX2

Fixes: 9484092baad3 ("eal/x86: optimize memcpy for AVX512 platforms")
