This gets rid of a number of FAILs with --target_board=native-extended-gdbserver. The fact that checkpointing does not work has nothing to do with dejagnu's native and remote concepts. It only works with native Linux targets because the implementation is currently baked with linux-nat.c. gdb/testsuite/ChangeLog: 2017-10-12 Pedro Alves <palves@redhat.com> Simon Marchi <simon.marchi@polymtl.ca> * gdb.base/checkpoint.exp: Don't check is_remote or isnative. Instead skip if there's any gdb_protocol set.
