Argh. But this seems doesn't work for extended-remote target:

(gdb) thread apply all print tlocal

Thread 9 (Thread 10463.10471):
Cannot find thread-local storage for Thread 10463.10471, executable file target:/tmp/t-thread:
Remote target failed to process qGetTLSAddr request

(gdbserver side with '--remote-debug' agrees with the above):

getpkt ("qGetTLSAddr:p28df.28e7,0,7f963e8a7330");  [no ack sent]
putpkt ("$E01#a6"); [noack mode]

Is my gdbserver is mis(configured|compiled) and do something wrong with libthread_db?
