Depends ...

... for implementing a new target or multilib and active development, 
I'd recommend using "rtems4.11"+accompanied toolchains, because this is 
were active development goes into.
... for "production works", I'd recommend using "rtems4.10"+accompanied 
toolchains, because they, except that still no tarball has been 
released, are "stable".

rtems4.9, though it's still officially labeled "stable", as far as I am 
concerned, and though some people will want to kill me for saying so, 
actually is de-facto "dead".

I.e. to the OP, I'd recommend rtems4.11 (comprising gcc-4.5.2, 
binutils-2.21). To you, rtems4.10 likely is the preferrable choice.
