    <p><font face="Calibri">Hi there! I've just tried ASan/MSan in my
        Clang 10.0.1 installation built from the monorepo tarball this
        way:</font></p>
    <p><font face="Calibri">export CC=/opt/gcc-9/bin/gcc<br>

    <p><font face="Calibri"><a href="https://github.com/llvm/llvm-project/releases/download/llvmorg-10.0.1/llvm-project-10.0.1.tar.xz" target="_blank" rel="noreferrer">https://github.com/llvm/llvm-project/releases/download/llvmorg-10.0.1/llvm-project-10.0.1.tar.xz</a><br>
      </font></p>
    <p>In that installation I am unable to use ASan/MSan as the
      corresponding libs are missing. Here is what I get when linking a
      small executable:</p>
    <p>/usr/bin/ld: cannot find
      /opt/llvm-10/lib/clang/10.0.1/lib/linux/libclang_rt.asan-x86_64.a:
      No such file or directory<br>
      /usr/bin/ld: cannot find
      /opt/llvm-10/lib/clang/10.0.1/lib/linux/libclang_rt.asan_cxx-x86_64.a:
      No such file or directory</p>
    <p>The normal builds work well and executables do function.<br>
    </p>
    <p>What am I missing? Do I have to enable an additional project for
      these libs to get built/installed? (The environment is Ubuntu
      16.04.2 x86-64, LLVM is built using GCC-9)<br>
    </p>
    <p>Thanks in advance,<br>
