Analogous to charon-nm the charon-tkm daemon is a specialized charon
instance used in combination with the trusted key manager (TKM) written
in Ada.
The charon-tkm is basically a copy of the charon-nm code which will
register it's own TKM specific plugins.
The daemon binary is built using the gprbuild utility. This is needed
because it uses the tkm-rpc Ada library and consequently the Ada
runtime. gprbuild takes care of the complete binding and linker steps
required to properly initialize the Ada runtime.
