configure tests the wrong compiler #179
Description
Extension modules are built with the compiler configured in distutils/setuptools.
When setup.py calls the configure script, it should pass this compiler.
This will eliminate this error seen in https://github.com/sagemath/cysignals/actions/runs/6227465351/job/16902173349:
