[libcxx-commits] [libcxx] Fix bug in documentation regarding dependencies. (PR #84930)

[via libcxx-commits]

https://github.com/EricWF created https://github.com/llvm/llvm-project/pull/84930

The docs for building modules suggest you have to build with -j1 and
build the std modules first. Fortunetly, that's just a bug in the
documentation. By correctly listing the libraries as dependencies,
the build system will order the builds correctly.
