This is another regression that I noticed on AIX.

The problem is that we had a check in xcoff_relocate_symtab that
was supposed to detect the case where we're debugging a core file.
The check was based on the inferior ptid being null. I replaced it
with a check against target_has_execution, which seemed more
appropriate.

Is there a routine that performs this check?

        Fix an error happening while loading symbols from a core file.

        * rs6000-nat.c (xcoff_relocate_symtab): Use target_has_execution
        to detect whether we're debugging a core file or not.

Tested on powerpc-aix. Checked in.
