This is 100% public and you should be able to access it. Having said that, Buildbot can be slow and sometimes just doesn't load. This particular build logs loads for me just fine _right now_.

That buildbot is `flang-aarch64-sharedlibs`, which is defined in llvm-zorg [here](https://github.com/llvm/llvm-zorg/blob/7424d711752e5b90a2daeda937f4a6dec47cd535/buildbot/osuosl/master/config/builders.py#L2331-L2344). You can use that definition to see what CMake flags are used for this config. For build failures like this you will very likely discover that adding: 
* `-DBUILD_SHARED_LIBS=ON` 

does the trick :) (as in, shared-libs configuration is much more sensitive to missing dependencies). Hope this helps, if not we'll dig a bit deeper 👍🏻 

Ah, and here's the actual CMake invoc from the failing buildbot job:
```bash
cmake -DLLVM_TARGETS_TO_BUILD=AArch64 -DBUILD_SHARED_LIBS=ON -DLLVM_BUILD_EXAMPLES=ON -DCMAKE_CXX_STANDARD=17 '-DLLVM_ENABLE_PROJECTS=mlir;llvm;clang;flang' -DLLVM_ENABLE_RUNTIMES=openmp -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=ON '-DLLVM_LIT_ARGS=-v -vv' -GNinja ../llvm-project/llvm
```
