  • Let llvm-config tell us where to find its tools
  • Add llvm-tblgen to rust-dev for cross-compiling

Fixes #86890.

Hmm, bootstrap's unit tests don't like trying to execute its mock llvm-config...

@cuviper I think you may need to change this to support --dry-run - does using dry run locally reproduce the test failure?

I checked out that try-commit and confirmed that ./x build --host i686-unknown-linux-gnu does find ci-llvm/bin/llvm-tblgen.

I also guarded this to not run llvm-config in dry runs. I didn't bother to set approximate paths, but I could if you want.

Thanks! No need to set dummy paths; the only thing it would be useful for is #102563 and we're planning to take a different approach there.
