 Are there any remote Alpha targets there in the first place?

 I only have writing Alpha/Linux gdbserver on my todo list once I'm done 
with the more urgent Alpha stuff (Linux kernel EV4 support restoration, 
GCC LRA conversion) and I haven't heard of any other Alpha GDB RSP debug 
stub either.  There *might* be something in QEMU; I guess that'd be the 
only place to check.
