Thanks Konstantin.

It looks like libcxxrt missing altogether:

    $ find /usr/local  -iname libcxxrt
    $

Let me build Clang from sources again and see if it shows up in the
build directory. Perhaps `make install` missed it.

Related: these sanitizers are awesome - they are finding obscure stuff
throughout all the projects being tested. Every engineering process
should include a Clang scan-build and sanitize run.
