java broken/miscompiled on i686

[Andreas Jaeger <aj at suse dot de>]

It seems that we have somehow an endless loop in java, most of the
libjava tests time out on i686-linux-gnu, the results are:

                === libjava tests ===

Schedule of variations:

Jeffrey, this could explain the long time you need for your nightly
bootstrap+testsuite runs.
