Bug report

Bug description:

blake2module.c may include _hacl/Hacl_Hash_Blake2b_Simd256.h and/or _hacl/Hacl_Hash_Blake2s_Simd128.h, and thus needs to compile with LIBHACL_SIMD128_FLAGS and/or LIBHACL_SIMD256_FLAGS, or you get an error like this if the compiler doesn't enable those SIMD features by default:

In file included from ./Modules/blake2module.c:139:
In file included from ./Modules/_hacl/Hacl_Hash_Blake2b_Simd256.h:42:
In file included from ./Modules/_hacl/libintvector.h:28:
/Library/Developer/CommandLineTools/usr/bin/../lib/clang/7.0.2/include/smmintrin.h:28:2: error: "SSE4.1 instruction set not enabled"

I would create a PR but unfortunately I can't figure out where this needs to be added.

CPython versions tested on:

3.14
