Steven Wallace a5e1a0f2e9 The recently introduced sv_sendsig entry of the sysentvec structure
is incorrectly set to 0, for the purpose of "ignoring" the signal.
This does not ignore the signal, but rather, executes the function
at location 0 in kernel mode, which shortly thereafter causes a panic.

The sv_sensig entry for ibcs2 emulation should be set to the system's
normal sendsig routine.
