The problem is that the simulators generate these signals (the
simulated environment supports them) but they're translated to the
hosts's SIG* values to "standardize" how they're handled by gdb.  If
the sim supports more signals than the host, there needs to be some
fake value they're translated into.

Not that I agree with the technique, but that's how it is...
