CONFIG_SECURITY_PATH is the one that is mandatory for TOMOYO 2.x but breaks the
kABI. But CONFIG_SECURITY_PATH is optional for AKARI. AKARI was designed to be
usable on RHEL kernels without changing kernel config or patching to source.

TOMOYO 1.x does not need CONFIG_SECURITY_PATH because TOMOYO 1.x adds a new set
of hooks similar to CONFIG_SECURITY_PATH. Thus, the kABI is preserved but
TOMOYO 1.x needs patching to source.
