I'm confused on the choice of "native" for name.
local-remote-host.exp/local-remote-host-notty.exp seem just or more
more native to me, as they assume a shared filesystem, while
the whole point of this one is emulate the case of _not_ sharing
the filesystem?

Why do we need to also use the board as a target board?

No biggie, but this:

  set_board_info gdb_opts "-d \"${tmp_dir}\""

looks a little simpler to me, just for the fact that it runs
through less code / fewer indirections in GDB.
