I couldn't run the test suite because

[13:48:09] ../meson.build:1:0: ERROR: Unable to detect linker for compiler `/opt/bin/x86_64-apple-darwin14-libgfortran4-cxx11-julia_version+1.7.3/x86_64-apple-darwin14-clang++ -Wl,--version -L/workspace/destdir/lib -fuse-ld=/opt/bin/x86_64-apple-darwin14-libgfortran4-cxx11-julia_version+1.7.3/x86_64-apple-darwin14-ld`

[13:48:09] clang-16: error: linker command failed with exit code 1 (use -v to see invocation)

That is, it fails because the Apple linkers aren't set up correctly. I think it's the same problem as JuliaPackaging/Yggdrasil#7745.

The meson build failure happens for me locally but not in CI.

We probably need to update BinaryBuilderBase first: https://github.com/JuliaPackaging/BinaryBuilderBase.jl/blob/6faea2ef758b089156f35716d0f55dc74a8ab786/test/Project.toml#L16

[eschnett]

This PR depends on JuliaPackaging/BinaryBuilderBase.jl#363.

This PR probably needs to disable ObjectFile 0.3. Should I do this, or should I add a function with a @static if condition to handle both versions?

[giordano]

Only v0.4 is fine

[eschnett]

It seems Manifest.toml is committed into the repository. Should I updated it as well? Or should I remove it?

[giordano]

I'm not a fan of committing the Manifest in packages, but let's update it for the time being.
