Restrict avx2 hack to windows target this workaround is possibly rather a windows & gcc specific problem. See e.g. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54412#c25 on Linux with gcc 8 this patch brings roughly a 8% speedup. However, probably needs some testing in the wild. includes a workaround for an old msys make (3.81) installation (fixes #2984) No functional change
