---------------------------
misc: README direct to website for dependencies

This patch updates the README to direct the user to the appropriate
sections on the gem5.org website rather than duplicating information.

Testing Done

I am fine with the patch as such.  I think we should either maintain the dependencies
here in this file or on the website.  I don't see why we would like maintain them in
two different places unless we can link them so that one reflects the other.

I agree that it would be nice, but I think the time it would take to develop something
automatic would far exceed the time needed to bump it when needed.

I suggest we remove the dependency stuff altogether from this file.  
We expect the users to read the documentation on the website anyway.

I'm happy with that. Anyone else got any thoughts on this one?

I agree.  Better to just replace the dependency text in the README with the URL for the appropriate wiki page, and then it will never be out of date again.  Maybe list the tools we currently depend on (without mentioning versions) so people know that they need more than just a C++ compiler, to encourage them to actually check the link, but specifically say that this list is just an example.
