Same error on x86 Debian Installed with X 3.x: https://buildbot.python.org/#/builders/1244/builds/3253

[vstinner]

"x86 Debian Non-Debug with X 3.x" and "x86 Debian Installed with X 3.x" workers are 32-bit machines, whereas Hacl_Hash_Blake2s_Simd128.c requires Lib_IntVector_Intrinsics_vec128 and Lib_IntVector_Intrinsics_vec128 is only defined on 64-bit architectures (#if defined(__x86_64__) || defined(_M_X64)).

Duplicate of gh-125244, but this will make searching for it a bit easier :)

Oh, I didn't realize that's a PR, not an issue. So this might as well stay open.

Good that a PR was proposed to fix the issue!
