The value of this option should specify the full pathname of the C/C++ Front

a program named <i>llvm-gcc</i> and the C/C++ FrontEnd install directory will
be inferred from the path found. If the option is not given, and no llvm-gcc
can be found in the path then a warning will be produced by

will fail as these libraries require llvm-gcc and llvm-g++. See
