    gdbserver: Clear .deps on clean
    
    In some situations, the dependency tracking files in .deps can refer to
    source files that were removed or renamed, leading to errors like:
    
      make: *** No rule to make target `version.c', needed by `version.o'. Stop.
    
    This patch makes the clean target clear the .deps directory, which gives
    the user a chance to recover from the error wihtout knowing about the
    internals of the build system.
    
    It is already done for GDB.  See here for more details:
