Some of your benchmarks are almost two times faster with Altivec on
powerpc, which is impressive. Please try the newest commit, which
enables Altivec for powerpc, and checks for Altivec at run-time.

I tested building the package using qemu-system-ppc, and it failed
gracefully during the tests with the expected error message, since
neither qemu-system-ppc nor qemu-system-ppc64 emulate Altivec.
