It's not quite that simple.

I think this is a case of someone blindly "fixing" a testsuite without any 
consideration of what is actually being implemented.

IMO a host core dump is for most purposes useless[1], and dumping guest state 
to a different location is a bug.  Given the choice between dumping guest core 
in the "normal" location and setting the WCOREDUMP flag, the former seems much 
more useful.

[1] A host core dump may be useful for debugging qemu itself, but that's a 
fairly specialized corner case, and not necessarily something we want to be 
exposing to users.
