SMP Tests Run Time

In investigating Jennifer's SMP test failure issues, it appears
that a combination of the backtrace only including global
symbols and the lengthy test execution time make these
pretty unsuitable on a simulator.

Daniel was nice enough to gather some data for us on smplock01

+ 1 minute on 200 Mhz NGMP w/L2 holding the entire application
   - expected to be 4x faster than LEON3
+ ~10 minutes for dual core on GRSIM
   - expected to be at least 20 if quad-core

Daniel projected/guessed 10-15s on a 1.2Ghz QorIQ

Can the longer running tests be scaled back in execution time and
meet their goals?

We plan to provide execution times for all as a reference point.
