It may have decided that they are used by uClibc's threading library.
Beyond here I do not think I can make any useful guesses; all the
logic is different between gdb and gdbserver.  You'd have to debug it.

If it's decided threading uses them, "handle SIGUSR1" should show
nostop noprint alreayd.  Otherwise, it may just never be notified of
the signal - that would be a bug somewhere.
