This fix seems to imply that there is something else wrong in the logic in
the build file. If the compiler does not support avx512, the fact that the
CPU supports it should be completely irrelevant. Therefore, I think a more
correct fix (logically) should be to remove the "i40e_avx512_cpu_support"
from the next "if" condition, and only check the compiler support. We
don't do anything with the cpu support variable.

Moreover, this patch doesn't resolve the issue [1].

Re: -fno-asynchronous-unwind-tables, when cross-compiling from Linux, I
observe bit-to-bit identical i40e_rxtx_vec_avx512.c.obj. My guess it that this
option somehow affects GCC inlining heuristics. Similar issue existed in
librte_acl (at least a year ago win GCC 6, I believe), where GCC generated
incorrect code unless certain functions had been inlined (caught by test
app). No an AVX expert, just my 2c.

Hi Thomas, David,
Do you prefer to get this directly to the main repo, since it is fixing the
windows build?

Given it will be pulled shortly, I think it's OK through next-net.
