Hi,
attached patch should fix the test failures on ppc64el [1].
Since the altivec optimizations for ppc64el use vsx functions like
vec_vsx_ld, it doesn't make sense to disable vsx if altivec is enabled
on ppc64el.
I tried to test this on qemu/ppc64el, but the linker segfaulted...
Best regards,
Andreas

Subject: [PATCH] configure: enable vsx together with altivec for ppc64el
The altivec optimizations on little endian ppc64 don't work without vsx.
