unloaded kernel modules.  Remove the example linux compat sysctls
  because they break if the linux emulator is loaded as a module, rather
  than compiled in.  Add a BUGS entry indicating as much.

If loadable kernel modules are used to introduce additional kernel
functionality and sysctls to manage that functionality, sysctl.conf may
be processed too early in the boot process to set those sysctls.
For example, sysctls to manage the linux emulator cannot be set in
sysctl.conf if the linux emulator is loaded as a module rather than
compiled into the kernel.
