Well, this is a more of an "upstream default" question rather than a 
"why don't you recompile speex" question, and one where it might make 
sense to come up with something reasonable across the board; either by 
upstreaming "fixed point by default for armhf", or by Debian to drop its 

It does not look likely to me that PulseAudio upstream and Debian would 
correspond to so different machine/user scenarios so that a Debian 
specific patch would make sense here.
