ld testsuite use of notarget

Much of the time it is better to use xfail rather than notarget to
hide a testsuite failure no one is planning on fixing.

1) When a target is fixed, an inappropriate xfail results in XPASS
   whereas notarget is silent.  Leaving in an inappropriate notarget
   entry risks the bug reappearing later, silently.
2) Tests might be used as a template for a new test, carrying over
   notarget and/or xfail.  Inappropriate notarget entries are silent.
3) An xfailed test that mysteriously XPASSes might actually indicate a
   bug.
