nasm/yasm not found or too old. Use --disable-x86asm for a crippled build.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user at ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

As part of the following recipe to get a ffmpeg/libvpx install that supports VP9 HDR Profile 2: 

git clone https://chromium.googlesource.com/webm/libvpx <https://chromium.googlesource.com/webm/libvpx>
cd libvpx
mkdir -p build
cd build
../configure --enable-vp9-highbitdepth
make -j16
cd ../..
git clone https://git.ffmpeg.org/ffmpeg.git <https://git.ffmpeg.org/ffmpeg.git>
cd ffmpeg
./configure --extra-ldflags=-L"$(pwd)/../libvpx/build" --extra-cflags=-I"$(pwd)/../libvpx/build" --enable-libvpx
make -j16

Here is the requested ffbuild log:
