Link object files without libSystem macOS

I'm writing a compiler for macOS on x86-64, but when I link the object files together, ld says 

ld: dynamic main executables must link with libSystem.dylib for inferred architecture x86_64

But since libSystem contains libc, I don't want to use it (it would give me lots of duplicates). How can I get around this?

Use -macosx_version_min 10.6 as ld parameter. This will generate LC_UNIXTHREAD instead of LC_MAIN in your executable. If you want even more control you'd need to get rid of ld in your chain altogether.
