Hi, I noticed this problem when I compiled llvm with following settings.

  $ cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=`pwd`/../testinstall -DLLVM_ENABLE_PROJECTS=clang -DLLVM_ENABLE_RUNTIMES="libcxx;libcxxabi;openmp" -DLLVM_TARGETS_TO_BUILD=X86 -DLLVM_RUNTIME_TARGETS=x86_64-unknown-linux-gnu -DLLVM_DISTRIBUTION_COMPONENTS="clang;runtimes;opt;llvm-link" $HOME/llvm-upstream/llvm-project/llvm

The build fails because of missing "--version-script" flag.  This is caused by failures of libomp linker tests like below.  These failures are caused by "unknown" in triple.

  $ ninja distribution
