Apart from the simulator, there will be a problem with the tm_print_insn
function.  There is only one, and the first _init_tdep that is called
will install its own.

I tried to have a look some day and see if we could use the opcodes generic
entry point but I stopped because there was some more work with some targets.

I'll be happy to test that.
