Create a macOS universal binary

baronfel commented 1 month ago

Adds a target that

creates arch-specific macos binaries
stitches them together using lipo to create a universal binary (thanks @rolfbjarne!)

Things we need to think about:

how are these signed/notarized?
how is the universal binary passed to the rest of the build process in the azdo pipelines?
How does the azdo pipeline on mac call the build? Because we'd need it to either call this new target directly or have this target be a dependency of the existing build entry point

Tested this on a m2 machine and it works as expected:

% file dotnet-core-uninstall 
dotnet-core-uninstall: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64:Mach-O 64-bit executable arm64]
dotnet-core-uninstall (for architecture x86_64):    Mach-O 64-bit executable x86_64
dotnet-core-uninstall (for architecture arm64): Mach-O 64-bit executable arm64

Don't think we do notarization for this.
