mk: disable gcc AVX512F support
This is a workaround to prevent a crash, which might be caused by optimization of newer gcc (7.3.0) on Intel Skylake. This disables AVX512F support of gcc by adding -mno-avx512f if it is disabled in DPDK (CONFIG_RTE_ENABLE_AVX512=n). This does not apply to the meson build as that doesn't have such an option but always enable AVX512F whenever supported.
