Bug#888219: ignition-math4: FTBFS on *i386: OrientedBoxTest.OperatorStreamOut fails

Package: ignition-math4
Version: 4.0.0+dfsg1-1
Followup-For: Bug #888219

Hello,

I can confirm that building with -ffloat-store fixes this issue on i386. 

https://launchpad.net/ubuntu/+source/ignition-math4/4.0.0+dfsg1-1ubuntu2/+build/14331366

Attached is the patch has been uploaded to Ubuntu to fix this issue there,
and is one possible solution.  (Though you may wish to adjust it to also do
the right thing on non-Linux i386 Debian architectures.)

Cheers,
