llvm-runtimes/libatomic-stub: new package, add 0 Clang(LLVM) implements atomic functions in compiler-rt, while GCC provides a dedicated libatomic for it. Some apps such as nodejs erroneously depend on GCC through libatomic. LLVM's atomic builtins and libatomic are source-compatible so such packages should be also buildable with LLVM. It would be hard to fix all those packages, so let's deal with it on compiler-rt side by installing a stub libatomic.a.
