Build that runs long on single CPU quickly fails on multiple CPUs with random
errors which don't occur in single CPU build.

> cd ../cmake -G "Unix Makefiles" ../llvm -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=/opt/llvm/current
> cmake -G "Unix Makefiles" ../llvm -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=/opt/llvm/current
> gmake -j 10

on FreeBSD 11.
