Fix gdb.base/remote.exp with native-extended-gdbserver board
This fixes gdb.base/remote.exp regressions caused by the previous
commit to the testcase, when tested with
--target_board=native-extended-gdbserver. For example:
...
show remote memory-write-packet-size
The memory-write-packet-size is 0 (default). Packets are limited to 16383 bytes.
(gdb) FAIL: gdb.base/remote.exp: write-packet default
...
With that board, GDB connects to GDBserver at gdb_start time, so GDB
is showing the actual remote/gdbserver packet size limits.
Fix it using the usual "disconnect" pattern. While at it, there's no
need to start GDB before compiling the testcase.
gdb/testsuite/ChangeLog:
2018-05-22 Pedro Alves <palves@redhat.com>
* gdb.base/remote.exp: Only gdb_start after compiling the
testcase. Issue "disconnect" before testing "set remote" command
defaults. Issue clean_restart before running to main.
