It was revealed by HJ's modification to check2() in string/test-strstr.c
to test for page boundary.  So arguably we are more or less covered.  In
fact for this particular bug we need it to be the case that the skipped-over
NUL value is in an address that is >= 4, mod 8, which happens to be true
in this case, but I'm not sure it was by design.

However, that test case does reliably catch this particular bug.  I think
I must not have re-checked the ILP32 build of glibc since committing the
optimized strstr in September, or else I just missed the FAIL from this one.
