macdeployqt always fails when run on universal apps (both arm64 + x86_64 slices).

macdeployqt always fails when run on universal apps (both arm64 + x86_64 slices).

macdeployqt always fails when run on universal apps. This reproduces for all apps (even hello world apps). I have included below details on why this happens. I ran macdeployqt with --verbose=3 for my analysis.

1.)  macdeployqt run install_name_tool to delete rpaths and add new rpaths. 'install_name_tool' gives error if the same path is passed twice to -delete_rpath.

So if you run install_name_tool like this, it would give an error, which is what macdeployqt does.

I have included below the log from macdeployqt. As you can see th path '/Users/mb12/Qt/6.4.2/macos/lib' is replicated twice.

Log:  using QList("-delete_rpath", "/Users/mb12/Documents/macos_version/universal_app_porting/build/qt-macos-arm64/Release", "-delete_rpath", "/Users/mb12/Qt/6.4.2/macos/lib", "-delete_rpath", "/Users/mb12/Documents/macos_version/universal_app_porting/build/qt-macos-arm64/Release", "-delete_rpath", "/Users/mb12/Qt/6.4.2/macos/lib", "-add_rpath", "@executable_path/../Frameworks")

2.) The path dupliccation happens because macdeployqt uses " otool -L " to determaine which paths to delete. On universal binaries, otool will show the same dependency twice, once for arm64 slice and once for x86_64 slice.

The duplicate dependency rpath needs to be handled by macdeployqt.
