Hi all,
I see a bunch of third party submodules in angle that don't seem to be deleted correctly.
I hit this problem while attempting to reproducibly clone the AOSP repo.
Before I submit a patch, I'd like to check if this is a known problem or if I'm missing something here.
Example error message:
```
Could not get list of submodules: external/angle:
Error fatal: No url found for submodule path 'third_party/OpenCL-ICD-Loader/src' in .gitmodules
```
Here's the list of submodules that are broken:
third_party/OpenCL-ICD-Loader/src
third_party/Python-Markdown
third_party/SwiftShader
third_party/VK-GL-CTS/src
third_party/android_deps

Thanks,
