For in-kernel modules in 2.6, they are actually built during 'make',
the modules_install target only installs them. Therefore, the switches
_do_ get used when the module is built.
External modules are obviously different (they can't be built when the
kernel is built), and the book needs to point out what you've reported.
/me suppresses the thought that proprietary modules and hardened systems
may not go together well.
