[compiler-rt] [compiler-rt] Link atomic against builtins (PR #65239)

[Petr Hosek via llvm-commits]

https://github.com/petrhosek created https://github.com/llvm/llvm-project/pull/65239:

The atomic shared library needs to be linked against builtins. The `add_compiler_rt_runtime` call already has `DEP builtins` but that only ensures that the `builtins` target is built before `clang_rt.atomic` but doesn't link against `clang_rt.builtins`, to do so we need to use `LINK_LIBS clang_rt.builtins`.
