The configure script incorrectly concludes that no Altivec code can be compiled
because just #including altivec.h throws an #error without specifying -maltivec
as well (and possibly vice versa). The attached patch fixes this by just trying
the four combinations of -maltivec or -faltivec with or without #including
altivec.h.
(Of course, debian/patches/100_relibtoolize.diff needs to be updated as
well to propagate the fix to the actual configure script)
