Build problems on amd64/armhf

[Benjamin Redelings <benjamin.redelings@gmail.com>]

Hi,

My software bali-phy is having build failures on amd64 with hardware 
floating-point (armhf) that don't occur on x86-64, and seemingly do not 
occur with software floating-point (armel).

    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=918047

The bug seems to come from NaN's getting generated on arm64/armhf that 
do not occur on x86-64.  Further inspection of the build log shows that 
the same bug occurs on hppa, but no other architectures.

I will investigate further (for example, turning off -ffast-math on 
x86-64) but the obvious route would be to run a debugger on hardware 
where the bug can be reproduced.  Any suggestions on how to deal with this?
