SIGILL reproducer on Montecito/NFS

1. compile this set by %make all
2. place 'testpattern' and 'test_nfs.sh' on nfs.
3. run test_nfs.sh

test_nfs.sh is adjusted to 8 cpu system (I used.)
If you have larger # of cpus, please rewrite

   testpattern 8 -> testpattern # of cpus.

This shell invokes 1000 trials and reports # of error.
