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.
