Describe the issue:

I am trying to build numpy 2.0.1 on AIX OS with ibm-clang_r compiler. numpy is using meson build in this version and I am hitting issue -

$ python -m build --wheel --no-isolation .

• Getting build dependencies for wheel...

seems linker ld on AIX does not support --version flag. tried few suggestion found on internet but could not get past this issue.

does meson build supported on AIX ? could some one please suggest way out from here?

PS - I was able to build numpy 1.26.4 which had setup.py . ( did not use meson build for this ) simply built whl file using python setup.py bdist_wheel, but with 2.0.1 this is not the case as setup.py is removed from this version and have to build using meson build.

Reproduce the code example:

$ python -m build --wheel --no-isolation .
