I see it when running libcxx tests (which link ~6000 executables), where around 3-6 of those linker jobs get stuck, without LLVM_LINK_LLVM_DYLIB, but with libc++ linked statically. FWIW, if you want to cherrypick this in one form or another, you'll need to pick dd7575ba44f0e255e3d3c04bc60648a8d41a18d4 <https://reviews.llvm.org/rGdd7575ba44f0e255e3d3c04bc60648a8d41a18d4> too (which I just went ahead and committed directly as trivial).
