Java test failures

[Mark Mitchell <mark at codesourcery dot com>]

On the branch, I see multiple Java failures along the lines of:

  FAIL: Thread_Wait execution from source compiled test
  FAIL: Thread_Wait execution from bytecode->native test
  FAIL: Thread_Wait -O execution from source compiled test

I assume this is because I did not configure with --enable-threads.

If Java doesn't work at all without --enable-threads, then it should
only be built if --enable-threads is specified.  Arguably,
--enable-threads could become the default on systems that support
threads, as well.

If some programs work and some don't, that's OK -- but then these
tests should be XFAIL'd when --enable-threads is not used.

Eliminating FAILs is important because it is only when tests are
normally expected to pass that new FAILs stand out.

Thanks,
