The kernel ABI is fairly stable.  There are only a few dozen syscalls,
and it's easy to write Ada wrappers for them.

It doesn't buy you that much because large parts of the GNAT run-time
on GNU systems rely on services provided by the C run-time library.
Tasking and I/O are examples.  Duplicating this infrastructure is the
hard work, and doing it right even for older kernels is quite a
challenge.
