See the full build.log attached. Compressed because it was 21 MB in size.

Expected results:

Build should finish. If I specify --with-system-libvpx, it seems to pass with libvpx-1.10.0. Note this is a x86 system.

And seems to work in 91.6.2, couldn't really find the "explaining factor" when diffing codebases. Oh well.
