Right now there is no way to do this. I had a patch for it long ago,
but it wasn't very nice, and I never had time to go back to it. You
could hack your GDB stub to ignore SIGALRM, in the same way that it
ignores certain threading-related signals (assuming you're using
gdbserver).

Are they in constructors? Google would be glad to tell you about the
problem, in that case.
