bfd-name

[Ben Elliston]

Moving onto the next problem :-), I see that cgen-generated simulators use
lookup_mach_by_bfd_name to see if the mach can run that object code (as
determined by sim_analyze_program and some BFD library calls).

What can be done to solve the problem of having a one-to-one correspondence
between mach and bfd name?  Suppose that the armv5 mach can load and execute
armv4 object files as well -- currently, unless these machs are entirely
specified, the sim will reject the armv4 object files.

Would it make sense to allow bfd-name to be a list of bfd names?

Thinking out loud,
Ben
