for the platforms i care about, they are ;).  but that's a fair point.  i 
think the reason i did this is because the signal_map logic isnt really used 
anywhere that i can see.  perhaps i should bite the bullet and add a 
target_strsignal() that operates on the callback maps ...

i get the feeling that the sim history is something like:
 - there were no viable sims, so this one was started up ... it was a bit 
bare, but it worked for people's minimal needs
 - ibm threw a lot of money at developers who created a pretty full ppc sim as 
a semi-fork ... then over time, much of that work was merged back
 - qemu gathered steam and sucked up all the potential developers
 - many cool sim features remain stalled & under developed
