The C runtime library is usually the interface to the OS kernel: in general all code will expect a C runtime library is available. I think you will need to build newlib or some other C library and I think the Ada runtime does contain some C code.

As an aside you could look into RTEMS: it's an OS for embedded systems with good Ada support.

There are sketch build instructions for RTEMS and Ada here:
