For that status, I have 2 ways to handle it:
1.  Change the "target empty" to other target, like "target remote
localhost:1234".
Then the remote target displace the empty target.  It can be use.

2.  In http://lkml.org/lkml/2010/1/3/28, there is a program called
s2c, it can convert some special message to a core file.  Then gdb can
parse core file.
If you think we need it, I can make it input the gdb commands.

Thanks,
Hui
