HACL Blake2 implementation does not check for `aligned_alloc` availability on macOS

[zanieb]

Bug report

Bug description:

In python-build-standalone, we support macOS 10.9. While this is really old and we can definitely bump to a newer version, we often find symbol references without guards when building CPython.

In this case, aligned_alloc is referenced in the HACL Blake2 implementation. aligned_alloc is only available in macOS 10.15+.

cpython-3.14> ./Modules/_hacl/Hacl_Hash_Blake2s_Simd128.c:523:40: error: 'aligned_alloc' is only available on macOS 10.15 or newer [-Werror,-Wunguarded-availability-new]

As a meta-note, I'm interested in submitting a patch to fix this and have opened #128135 to help avoid future regressions.

[picnixz]

I think this should be addressed upstream. Everything under Modules/_hacl/* is managed externally except the refresh.sh script and the README (and perhaps other text files).

cc @msprotz as our HACL* contact

Well.. technically, we could do something and not include those headers? since it seems to only concern the SIMD-128 version, we could add a configure check for that. Tell me which way is preferred.

[zanieb]

Sorry I just looked at the code and noticed that this was patched in #127932 (a couple days ago) and is a duplicate of #127897

[picnixz]

Closing as a duplicate of #127897.
