>Description:
I built gdb 6.8 for mpc5121 using instructions from http://www.crossplatform.ru/?q=node/385 and started gdbserver on a the remote target on a very simple multi threaded app:
================= CUT HERE ====================
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <pthread.h>

#define NUM_THREADS     5

{
	int c = 0;
   int tid;
   tid = (int)threadid;

   while (++c < 100) {
   printf("Hello World! It's me, thread #%d!\n", tid);

   }
   pthread_exit(NULL);
}

int main (int argc, char *argv[])
{
	printf ("Hello world\n");
   pthread_t threads[NUM_THREADS];
   int rc, t;
   for(t=0; t<NUM_THREADS; t++){
      printf("In main: creating thread %d\n", t);
      rc = pthread_create(&threads[t], NULL, PrintHello, (void *)t);
      if (rc){
         printf("ERROR; return code from pthread_create() is %d\n", rc);
         exit(-1);
      }
   }
   pthread_exit(NULL);
}

I used the cross gdb on a 686 host, setting the right sysroot, but I cannot set any breakpoints on the remote target. If I continue the program, I get..
