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.
I've come up with a patch which I beleive should fix this but
building with qemu is extremely slow and in any case to properly
test this really needs hardware both with (to do the build) and
without (to test it) altivec to properly test.
anyone on debian-powerpc have access to both and willing to test this?
