Then this is not a xfail but rather the dg-final should be skipped for ilp32.
xfail means the failure can be fixed in the future but in this case,
the failure is not fixable.
Something like:
{ target { !ilp32 } }
or (what I used in my changes which I was going to submit but had
higher priorities than submitting testcase fixes):
{ target { lp64 } }
