I suppose my main concern here is that the gdb/gdbserver unification
project will end up needing to reimplement chunks of libiberty.
But that would be a bad result, since libiberty already exists.

I don't really care so much about this particular function.
It is small, it doesn't really matter.  The xstrndup name is better
(IMO), but unimportantly so.
