Fix gcc 7.5 compilation error for zen4 and above configs

Browse Source 
For gcc greater than or equal to 7.0 version added AVX512 compiler flags
    in makde_defs.mk and make_defs.cmake. AVX512VNNI compiler flag is only
    supported from gcc version 8 or greater. So added another else condition
    for gcc version greater than or equal to 7 - enabling avx512 flags.
    This enables compilation of AVX512 assembly code paths with gcc 7.5 version.
