SR-13362: no baseline is available for the standard library on ASi

The standard library on non-Intel targets get compared to the baseline
from the Intel targets which is not guaranteed to be identical.  Mark
the checks as expected failures on non-x86_64 targets.  Although this is
entirely unsatisfying, it allows progress in the short term.
