You're doing the right test.  The issue is that core_pid_to_str
calls into the gdbarch_core_pid_to_str, and that isn't expecting
to be passed a "process pid" instead of an "LWP pid".

Could you try this one when you have a chance?  This is rebased on
top of current mainline, so it restores the elfcore_write_pstatus
call that the Unixware-excise patch removed.  I made sure it builds with
--enable-targets=all.

Thanks!
