This is wrong, because it doesn't create a directory named `clang' under
$LLVM_SRC_ROOT/tools. Rename the directory created by the last tar
command (`cfe-3.3.src') to `clang' and reconfigure.

P.S.: it is recommended to use a separate build directory instead of
building on the directory where the source code is.
