The armel build of cgal failed because fetestround() always determines
the mode to be FE_TONEAREST, despite nominally successful attempts to
specify other modes via fesetround():

  debian/tests/rounding_modes_simple
  fegetround() = FE_TONEAREST
  fesetround (FE_TOWARDZERO)
  fegetround() = FE_TOWARDZERO   (ok)
  fetestround() = FE_TONEAREST   (error)
  fesetround (FE_UPWARD)
  fegetround() = FE_UPWARD   (ok)
  fetestround() = FE_TONEAREST   (error)
  fesetround (FE_DOWNWARD)
  fegetround() = FE_DOWNWARD   (ok)
  fetestround() = FE_TONEAREST   (error)
  fesetround (FE_TONEAREST)
  fegetround() = FE_TONEAREST   (ok)
  fetestround() = FE_TONEAREST   (ok)

Could you please take a look?

Thanks!

This is a known problem. FPU rounding mode control is a crucial requirement for
CGAL, but armel does not support it. The flag itself is changed, but the test
shows that the FPU (or rather the emulation code) does not observe it.

Lowering severity since it never worked on armel (there are some ancient
binaries for wheezy, but they did not work).
