The generic kernel image must have module signing disabled so it can
load kernel modules from all vendors. Unfortunately loading a signed
kernel module into a kernel with module signing disabled will fail
because struct module_layout (which appears in kernel modules) contains
struct module, and struct module contains the sig_ok field, which is
conditionally compiled depending on CONFIG_MODULE_SIG (module signing).
Unconditionally compile the sig_ok field to work around this problem.
