You actually need only one good GNAT binary to start with.  With this one
you can build cross compilers for the other platforms where bootstrapping
is more difficult, from which you can build native compilers that are
finally used for bootstrapping.  That's how I built Ada compilers for our
distribution (starting with i386 as cross host, then ia64, alpha and ppc).
