compiled system image incorrect when building on GitHub Action MacOS-latest with Manifest.toml

[Roger-luo]

This happened when I commit the Manifest.toml to the repo and build it using this github Action:
https://github.com/Roger-luo/IonCLI.jl/blob/master/.github/workflows/sysimg.yml

Everything works fine when there was no Manifest.toml in the repo, but when I build with Manifest.toml on GitHub action, after I download the system image and use it locally with -J option, I got

ERROR: could not load library "/Users/jc/.julia/packages/IonCLI/DJ2Ch/deps/lib/libion.dylib"
dlopen(/Users/jc/.julia/packages/IonCLI/DJ2Ch/deps/lib/libion.dylib, 6): no suitable image found.  Did find:
	/Users/jc/.julia/packages/IonCLI/DJ2Ch/deps/lib/libion.dylib: unknown file type, first eight bytes: 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
	/Users/jc/.julia/packages/IonCLI/DJ2Ch/deps/lib/libion.dylib: stat() failed with errno=38

so I use nm to check if there are any symbols compiled into this system image, but there is no symbols at all, e.g this image

https://github.com/Roger-luo/IonCLI.jl/releases/download/v0.4.6%2B1/ion-1.5.0-darwin-x86_64.tar.gz

I'm not sure if I'm doing something wrong, since the only difference between the working one is a Manifest.toml, the build script basically just calls PackageCompiler.create_sysimage: https://github.com/Roger-luo/Comonicon.jl/blob/master/src/tools/build.jl#L317

and it seems to be MacOS specific, Linux works just fine. However, when I build it locally on my own Macbook, it works fine too. My Macbook has the same MacOS minor version with GitHub Action. So I really have no idea why this doesn't work... Anyone could help me?

for whoever wants to try themselves, I tagged different versions to build with or without a Manifest.toml:

with Manifest.toml: https://github.com/Roger-luo/IonCLI.jl/releases/tag/v0.4.6
without: https://github.com/Roger-luo/IonCLI.jl/releases/tag/v0.4.5

I find out why, this is because I was using cpu_target=x86_64 but it seems there are some issues building using this target on github action runners for MacOS. It should use the default app cpu_target suggested by PackageCompiler.
