 While working on #16667, I noticed that the build system for Cython code
 in Sage (a.k.a. `sage -b`) no longer detects `c_lib` headers as
 dependency: changing `src/c_lib/include/interrupt.h` for example should
 cause many files to be recompiled.

 The problem seems to be that the `include_dirs` in `src/setup.py` are sent
 only to distutils, not to Cython.
