AFAIK parts of the Kernel rely on inline functions and other compiler
specific features which are disabled when using -O0. Therefore, the
Kernel Makefile only allows either Os or O2. Of course it's possible to
compile particular modules using -O0.

Actually, these optimization flags still allows debugging, there might
only come up some strange side effects while stepping through the code.
