In order to keep up to date with changes to the libraries that `llvm-config` spits out, the dependencies to the LLVM are a dynamically generated rust file. This file is now automatically updated whenever LLVM is updated to get kept up-to-date. At the same time, this cleans out some old cruft which isn't necessary in the makefiles in terms of dependencies. Closes #10745 Closes #10744
