   @masayuki2009 I had to make an additional change to use `lookup_symbol` instead of `lookup_global_symbol` which returns a tuple with the first value as the symbol (or None).
   
   `python if (type(gdb.lookup_symbol("stm32_fpuconfig")[0]) is gdb.Symbol) : \`
   
   ```
   (gdb) info_nxthreads 
     0 Thread 0x24000358  (Name: Idle Task, State: Running, Priority: 0) 0x800238e in nx_start()
     1 Thread 0x380002f0  (Name: hpwork, State: Waiting,Signal, Priority: 224) 0x80091bc in arm_switchcontext()
     2 Thread 0x38000ec0  (Name: lpwork, State: Waiting,Signal, Priority: 100) 0x80091bc in arm_switchcontext()

   * 4 Thread 0x38002710  (Name: usbhost, State: Waiting,Semaphore, Priority: 100) 0x80091bc in arm_switchcontext()
   ```
   
   There are 22 different definitions of this {}_fpuconfig symbol so I am not quite sure what the change should be here.
