the llvm apt repo was removed and finding the exact rev of the llvm
toolchain that worked perfecting in our dockerfile is a problem.
We looked at the reasons why we were using this version of clang and it
appears to be this compiler warning.
`was built for newer OSX version (10.11) than being linked
(10.6)`
When you look at the dockerfile this makes sense.
```
ENV OSX_SDK MacOSX10.11.sdk
ENV OSX_CROSS_COMMIT 8aa9b71a394905e6c5f4b59e2b97b87a004658a4
RUN set -x \
&& export OSXCROSS_PATH="/osxcross" \
&& git clone https://github.com/tpoechtrager/osxcross.git $OSXCROSS_PATH \
&& ( cd $OSXCROSS_PATH && git checkout -q $OSX_CROSS_COMMIT) \
&& curl -sSL https://s3.dockerproject.org/darwin/v2/${OSX_SDK}.tar.xz -o "${OSXCROSS_PATH}/tarballs/${OSX_SDK}.tar.xz" \
&& UNATTENDED=yes OSX_VERSION_MIN=10.6 ${OSXCROSS_PATH}/build.sh
ENV PATH /osxcross/target/bin:$PATH
```
We are basically using the 10.11 sdk but linking to 10.6 as the
min version so this warning should be expected.
Also the docs on the osxcross project require clan 3.2+, not 3.8.
