Environment

- **OS**: Fedora 40beta
- **Sage Version**: 10-4beta0

Steps To Reproduce

Fedora 40beta has just arrived, I wanted to check if sage can be built. The first problem is that Fedora 40 is using gcc 14. Instead of using gcc package, I changed spkg-configure.m4 in build/pkgs/gcc and build/pkgs/gfortran to allow gcc 14.

The compilation gave an error for givaro; the patch in linbox-team/givaro#226 works for this. Next problem was with linbox. As a bypass, I used the changed files in #35148. The three packages have been successfully built.

But I stuck at the compilation of sagelib, apparently with ginac but not sure, see the package log
