looking at the build log -maltivec seems to be the smoking gun. It 
appears the upstream configure script is looking for altivec support at 
build time and enabling it if it detects it (which is the right thing to 
do when building for your own system but the WRONG thing to do when 
building distribution packages)

Ideally this sort of issue needs access to ppc hardware both with and 
without altivec to nail it down (you need to do the builds on machines 
with altivec support and then check they work on machines without it) . 
I'll try to take a look using qemu but I can't promise anything.
