Well, if you explicitly tell it that it's not an IEEE system, don't
expect IEEE concepts like NaN and Inf to work. This can't be the right
solution. I believe someone else managed to get it past that floating
exception thing at some point? 

'Configure' is no more intelligent than the people who write the
scripts, it has some generic checks and searches that it can try, but
most systems need some last minor tweak to come out right. So on
systems where we have sparse information on what is needed to get
things to work, strange things happen.

Now who was it that got it to work?
