Aren't there compiler flags that tell gcc it isn't operating in a hosted(?) environment, and hence not to emit calls to these functions? If so, I imagine they should be added to the kernel's core (or ARM arch ) makefiles.

IIRC there's some intrinsics (usually for operations like divisions) which GCC expects to be provided even in a free standing environment.
