Try "pragma No_Run_Time" in your gnat.ads file. It says "don't
generate _anything_ not directly required by my code", in effect.

"pragma No_Run_Time" may not be supported by this version. Look in the
gnat rm for similar pragmas; I think there is one to suppress the enum
stuff. 

Note that No_Run_Time is not documented.

Well, GNAT is not normally used to build kernels, and kernels are
_not_ like typical user programs. So I would not be surprised to need
some extra compiler/linker options. I'd call that a "solution", if
there is not a GNAT pragma that does what you need.
