The last batch of gcc 3.2.1 RPMs included GNAT/RTEMS for the i386, sparc, 
powerpc, and mips targets.

I haven't tried it but would think that if you could build the native
gnat from gcc 3.2.1, then you should be able to build GNAT/RTEMS.  You
need to use the same version native compiler as you are building 
cross.
