https://github.com/llvm/llvm-project/pull/147948 causes breaking of Cygwin build.
```
/home/kikai/llvm-origin-main/llvm/lib/Support/BLAKE3/blake3_dispatch.c: 関数 ‘blake3_xof_many’ 内:
/home/kikai/llvm-origin-main/llvm/lib/Support/BLAKE3/blake3_dispatch.c:241:5: エラー: implicit declaration of function ‘blake3_xof_many_avx512’; did you mean ‘blake3_hash_many_a avx512’? [-Wimplicit-function-declaration]
241 | blake3_xof_many_avx512(cv, block, block_len, counter, flags, out, outblocks);
| ^~~~~~~~~~~~~~~~~~~~~~
| blake3_hash_many_avx512
```
I've reported for upstream: https://github.com/BLAKE3-team/BLAKE3/issues/494
There are possibly workarounds:
1. Patch blake3 itself
2. Use `blake3_avx512.c` instead of assembly on Cygwin
3. Define `_WIN32` for compiling `blake3_dispatch.c`
I'm not sure which of these approaches would be the most appropriate, so I'd appreciate any suggestions.
Once there's a consensus, I'm happy to submit a PR accordingly.
