   Consider a GDB which has been built to support several different ISA's
   (a mips4111, mips4300, ...).  What architecture should GDB select by
   default when it goes to talk to a remote target?

I don't think it should be BFD's place to choose GDB's default target
architecture.  BFD is just an object file reader.  GDB should assume
an architecture compatible with the executable it is handed, and it
should try to get it from the remote target if possible.  If neither
is helpful or available, the default should be defined in GDB's
configury somewhere.
