Hello Jan,
   I don't know much about compiling with `dub`. But I think that 
the program invoking the linker defines the mode of the linker; 
looks like the linker is called from an x86_64 binary, instead of 
an arm64.

Can you tell us (use `file ...` to check):
1. Is `ldc2` an arm64 binary or an x86_64 binary?
2. is `dub` arm64?

I think in an ideal world you don't even have to tell `dub` what 
arch to build for, it automatically selects the right 
architecture.
If you use the LDC released binaries for macOS from LDC's github, 
you will get arm64 versions of `ldc2`, `dub`, ...
