Compiler Inconsistency During python-ibmdb Installation on AIX 7.1 vs AIX 7.3 #5102
Description
setuptools version
80.9.0
Python version
python 3.9
OS
Aix
Additional environment information
While installing the python-ibmdb driver, the build process behaves inconsistently across AIX versions:
On AIX 7.1, the C extension is compiled using GCC.
On AIX 7.3, it defaults to XLC, even though GCC is available on the system.
Installation logs for both AIX 7.1 and AIX 7.3 builds are attached for reference.
Is there a specific reason why the build process prefers XLC on AIX 7.3, even when GCC is available?

Expected behavior
With Aix7.3 also should compile with gcc compiler instead of xlc.
How to Reproduce
pip3 install ibm_db --no-cache-dir -v
Output
Reference logs for both AIX7.1 and AIX 7.3 attached.
