Bug#798718: opensurgsim: FTBFS on mips(el) and s390x: TimerTest fails

[Aaron M. Ucko]

Source: opensurgsim
Version: 0.6.0-2
Severity: important
Justification: fails to build from source

Builds of opensurgsim on mips, mipsel, and s390x all failed with
errors in SurgSimFrameworkTest's TimerTest, along the following lines:

  [ RUN      ] TimerTest.SettingFrames
  /«PKGBUILDDIR»/SurgSim/Framework/UnitTests/TimerTest.cpp:44: Failure
  Value of: timer->getLastFrameRate()
    Actual: 34156.5
  Expected: timer->getAverageFrameRate()
  Which is: nan
  /«PKGBUILDDIR»/SurgSim/Framework/UnitTests/TimerTest.cpp:45: Failure
  Value of: timer->getLastFramePeriod()
    Actual: 2.9277e-05
  Expected: timer->getAverageFramePeriod()
  Which is: nan
  /«PKGBUILDDIR»/SurgSim/Framework/UnitTests/TimerTest.cpp:46: Failure
  Value of: timer->getCumulativeTime()
    Actual: nan
  Expected: timer->getLastFramePeriod()
  Which is: 2.9277e-05
  [  FAILED  ] TimerTest.SettingFrames (1 ms)
  [ RUN      ] TimerTest.Comparison
  /«PKGBUILDDIR»/SurgSim/Framework/UnitTests/TimerTest.cpp:74: Failure
  Expected: (timer1->getAverageFramePeriod()) >= 
(timer2->getAverageFramePeriod()), actual: nan vs nan
  /«PKGBUILDDIR»/SurgSim/Framework/UnitTests/TimerTest.cpp:75: Failure
  Expected: (timer1->getCumulativeTime()) > (timer1->getLastFramePeriod()), 
actual: nan vs 2.4686e-05
  [  FAILED  ] TimerTest.Comparison (7 ms)

Both tests failed on mips and mipsel, but only TimerTest.SettingFrames
failed on s390x.  Could you please take a look?

Thanks!
