I didn't see any comments on this.  I'm pretty confident that no one
uses this protocol any more, so I would like to remove it, unless
anyone objects.

So, please speak up, if you object to "target rdp" being removed from
the arm-elf target.  No other triplet enables it.

(I had to apply a global interface change to remote-rdp.c today,
which reminded me.  Many of these remote targets I'm patching
deserve to be removed.  Let's make sure to get a complete list
before the next release...)
