I prefer this to a bunch of compiler flags. But I'm not expert on what is "correct"
This is for floating point errors that crept in with AVX512 instruction sets on some CI architectures.

This is similar to matplotlib#22132 in that NumPy has added more code paths that now take advantage of AVX512 optimizations and causes slight variations in results. Fixes matplotlib#24060
