Two good places to look for imformation are:
GCC installation help: http://gcc.gnu.org/install/
CrossGCC FAQ: http://www.objsw.com/CrossGCC/
Actually, the FAQ is a bit old - the build process is still the same,
though you should use the latest version available of the packages.
Here's what you'll need:
newlib-1.9.0
binutils-2.11.2
gcc-3.02
You can get these from http://www.gnu.org and http://sources.redhat.com.
I'd give a look to a recen post, also:
http://gcc.gnu.org/ml/gcc-help/2001-11/msg00221.html.
Actually, compiling for those UNIX systems, I don't know wether or not you
need newlib. I think you should be fine with the system's libc, but then I
don't know about telling your cross-compiler about those systems library
headers.
Somebody with more experience might give more help on this.

I don't know of any precompiled binaries for gcc cross-compiler.
