[inlining-demo] Fuchsia won't build with clang checkout provided by /third_party/clang/${platform}

[ioana-ghiban-arm]

Hello! When attempting building Fuchsia, clang throws this error:
cannot compress debug sections (zstd not enabled) [-Werror,-Wdebug-compression-unavailable]
You should be able to reproduce it with this setup:
Fuchsia git hash c5b68f7dd77 which uses 8280651ad57 clang hash
OS: Ubuntu 22.04.4 LTS

Due to this I am not able to go through the whole demo and try out MLGO as suggested.
Would immensely appreciate a fix or suggested workaround so I can see the framework in action.
Thank you.

There were recently some build breaking changes on the Fuchsia side, and @petrhosek has been working to fix them and then we can update the demo.
