It looks like encoding this information into the binary isn't working, but passing it via linker flags works just fine. Someone (not me) will have to repurpose the OSX version...

If no one picks this up, I'm going to start downgrading all macOS pipelines to ignore failures, as this is blocking other work.

Alright, looks like maybe `-platform_version 10.9` passing CI the first time was a fluke.

`-ld_classic` gets us further, then fails later in the expected way.

Removing macOS as a required pipeline.
