macOS: Workaround for buggy XCode 15.0 - 15.2 linker.

Thanks to Carlo Cabrera.

(cherry picked from commit b2915e9)

The previous commit removes emitting the `.subsections_via_symbols`
[1][2] directive for macOS. Nevertheless, the aforementioned Xcode linker
versions produce incorrect code for the VM without this directive.

As a fix for old versions of macOS, this patch adds emitting this
directive in the buildvm.
