Log Message:
>From tkoeppe@github: Specify SA_ONSTACK when setting up a signal
handler.  This allows the handler to use the alternate signal stack
if one is available in the handling thread, but has no effect
otherwise.

This change makes the signal handler respect existing choices
better. Specifically, this allows signal handlers to be set when
the process includes a Go runtime, since Go enforces that all signal
handlers in the process use the SA_ONSTACK flag (e.g. see
golang/go#20400).
