For anyone that doesn't want to maintain a fork of chromium, just download the PDB and hook it at runtime for spoofing and/or dumping call logs. For hook itself just add your dll as a dependency in the PE structure.
ELF and PE are functionally the same, instead of DLL's you load SharedObject as your injeciton method, but you don't need that at all since you can inject libraries in linux since it's a built-in feature.
