Subject: [PATCH] depends: add mold & ld.lld to gen_id

We use `lld` when cross-compiling for macOS, and it's version should
be tied to LLVM. However someone compiling with GCC and `-fuse-ld=lld`
would not see a cache bust if the LLVM toolchain was updated.

We don't use `mold` directly, but I'm aware of it's usage in
infrastructure, along with depends, used to test the project.
