This caused links to fail with:

> Enable chained fixups in lld when all platform and version criteria are
> met. This is an attempt at simplifying the logic used in ld 907:
>
> 93d74eafc3/src/ld/Options.cpp (L5458-L5549)
>
> Some changes were made to simplify the logic:
> - only enable chained fixups for macOS from 13.0 to avoid the arch check
> - only enable chained fixups for iphonesimulator from 16.0 to avoid the
> arch check
> - don't enable chained fixups for not specifically listed platforms
> - don't enable chained fixups for arm64_32
