Fix compilation problem with latest clang 

The change was introduced in the llvm-project repo here:
105c913156

The goal is to be able to pass a nullptr directory
to the LookupFile function if we are not interested
in retrieving the current directory, instead of
creating a dummy variable that is not used after
the function is called.

Fixes #996
