Build for linux-ppc64le, pip install fails

[olafthiele]

Im working on an IBM Power VM and there seems to be no wheel for it. How would I build one myself if there is none?

Python 3.6
Ubuntu 18

Thanks for a great project

Root cause is missing support in WebRTC and it doesn't look like it's coming soon:

Just for anyone else with the same problem, I was able to install webrtcvad by "faking" a little-endian ARM64 environment:

pip install --global-option=build_ext --global-option="-DWEBRTC_ARCH_LITTLE_ENDIAN" --global-option="-D__aarch64__" webrtcvad

@valterf Great idea, thanks for sharing
