Poul-Henning Kamp 895a7e604d Pull in fix from upstream NetBSD rev. 1.5: ...

If Unwind_Backtrace is broken, ctx.n will still contain ~0, and we will
    return that which poor behavior for the user, so return 0 instead.
    We could document ~0 to be an error, but that would deviate from the
    Linux behavior which is not desirable. Noted by Poul-Henning Kamp
