Re: FIP test results

[veach@caldera.com]

I am testing a _real_ runtime environment with the test suite, but I see
that the test is, in fact, calling chroot before trying to exec the
binary in question.  I also see a comment in the source file that says
pretty much what Matt pointed out -- FIP result returned because there
were no shared libs in the chroot'd location.
