Re: RFC: Deprecate the ARM simulator

I am totally OK with just deleting the arm sim altogether.
I was just not sure if there was a GDB approved method for doing so.

So instead of the deprecating patch, how about this one to add the sim
directory to the top level configure script's noconfigdirs list for ARM
targets:

(Obviously a full patch would include the regenerated configure file
file.  I am just posting this patch for discussion purposes).

I am also assuming that this patch, or something similar, should go in first
before any simulator sources are actually deleted...
