Turns out it's not that simple - of course. runtime->get_variable is just a
void pointer. The old arm stub was casting it by virtue of assignment to a
function pointer variable.
The x86_64 appears to be doing bypassing all the compile-time type checking by
passing the arguments through an ellipsis and then fixing up the argument list
in the ->call() function.
What I've changed the ARM and ARM64 things to is:
#define efi_call_runtime(f, ...) ((efi_##f##_t
*)sys_table_arg->runtime->f)(__VA_ARGS__)
