As for now, `extract_symbols.py` uses a predefined set of tools, none of which can read bitcode files. The patch makes it possible to override the used tool and passes a fresh built `llvm-nm` for that for multi-staged LTO builds. This fixes building plugins with LTO builds and subsequently makes `clang/test/Frontend/plugin-*` tests pass.
