Have a look at the ``(gdb) set mips'' command ;-)  Another group with 
the same problem are the ``info'' commands.

New targets, when someone remembers, are done this way.  The problem is 
all the old commands and for that we have have a deprecate mechanism.

The mailing lists also contain discussion about a set [<arch>] 
disassembler command which would more directly tie into bfd's 
disassembler option.
