No good reason. It's historical ugliness.

I'm not entirely sure any more; it's been ages since I looked at these.
I think the SIM_SIG* constants may be older than the TARGET_SIGNAL_*
constants; I don't think we need both... but I really don't know. The
problem is that a given int variable could hold any of the three right
now.

It's a righteous mess.
